ui: Replace per-conversation MCP overrides with per-conversation tool policy (#27745)
* ui: replace per-conversation MCP overrides with per-conversation tool policy
MCP server enabled state is now global (server.enabled); per-conversation
control moves to disabled tool keys and categories seeded into each new
conversation. Aligns the add sheet with the dropdown options and flattens
MCP tool groups in the tools submenu.

* ui: keep tool policy migration running when defaults parse fails
A corrupt disabledToolKeys localStorage entry no longer aborts the
migration; it falls through with empty defaults so legacy MCP server
overrides still get converted.
Assisted-by: pi
* ui: fall back to global defaults when agentic flow has no tool policy
Passing empty disabled sets bypassed the global defaults and could
enable tools for callers that do not pass a policy yet.
Assisted-by: pi
* ui: align preferences section headers with their methods
The Reasoning Effort and Working Directory headers sat above tool
policy methods; move them above setCwd and setReasoningEffort. Also
clarify the disabled tools JSDoc: existing rows with an unset field
have an empty policy, defaults apply only when there is no active
conversation.

* ui: gate MCP server avatars on conversation tool policy
Servers whose tools are disabled for the current conversation (MCP
category or server-scoped key) no longer show as enabled for the chat.
Assisted-by: pi
* ui: drop unused MCP category toggle from tools panel hook
Per-conversation MCP control is server-granular; no component renders
a whole-category toggle, so remove the dead API.
Assisted-by: pi
* ui: skip MCP init when flow policy disables the MCP category
Resolve the effective tool policy before deciding whether to
initialize MCP so flows that will not send any MCP tools skip the
init work. Callers without a policy keep falling back to global
defaults.

* chore: format
* ui: restore reasoning section in mobile add sheet
The sheet rewrite dropped it; the desktop dropdown still has it.
MCP Prompts and Resources stay out of the sheet on purpose.
Assisted-by: pi
* ui: clear MCP server group key in enableAllToolsForServer
The group key disables every tool of the server regardless of
per-tool keys, so re-enabling a server from Settings did nothing
while it was set.
Assisted-by: pi
* ui: skip MCP init when no policy-enabled server remains
Extends the category-level check: the flow also skips MCP init when
every globally-enabled server has its server-scoped group key
disabled in the tool policy.
Assisted-by: pi
* ui: make Settings tools tab edit defaults with category toggles
Adds per-category checkboxes and a caption stating the tab applies
to new conversations; tool picks inside a chat only affect that
chat.
Assisted-by: pi
* ui: gate cwd picker and mention picker on effective tool policy
Both checked the global disabled set directly, so a conversation
that disabled file_search still showed search as available.
Assisted-by: pi
* ui: clean up tool key helpers and store docs
Documents getEnabledToolsForLLM properly, unstacks the JSDoc at
isEntryEnabled, makes setToolEnabled persist like setCategoryEnabled
(toggleTool now delegates to it), and routes the serverId-less MCP
branch of toolKey through getMcpServerToolsKey so both key formats
come from one place. Preferences banner comments become plain
comments so they no longer read as class member docs.

* ui: indeterminate group checkboxes and inert grayed rows
A category that is on with nothing enabled under it now shows the
mixed checkbox state instead of a checked box next to 0/N. Rows
grayed out by a disabled parent no longer stay clickable behind
opacity.
Assisted-by: pi
* ui: gate MCP prompt and resource capabilities on tool policy
hasPromptsCapability and hasResourcesCapability accept an optional
set of usable server ids; ChatFormActions resolves it from global
enablement minus the active conversation's policy. Restores the
per-chat gating the old mcpServerOverrides provided; callers without
arguments keep global behavior.
Assisted-by: pi
* ui: remove unmounted MCP submenu component
Never rendered anywhere; its entries are duplicates (prompts and
resources live in the attachment menu, servers in the add menu and
sheet) that would need capability wiring maintained for nothing.
Assisted-by: pi
* ui: fix model information dialog width on all screen sizes
The dialog sets container-type: inline-size, so auto width ignores
its contents and collapses to padding. Give it an explicit viewport
width on mobile and cap at 60rem on desktop.
Assisted-by: pi
* ui: scroll wide chat template in model information dialog
Long unbreakable Jinja tokens blew out the table and dialog width;
the block now scrolls horizontally instead of stretching.
Assisted-by: pi
* ui: use fixed table layout in model information dialog
Auto table layout sizes columns to content min-content, so the chat
template's long lines kept inflating the dialog despite the scroll
wrapper. Fixed layout pins the first column and gives the value
column a definite width the wrapper can scroll within. min-w-0 on
the grid item guards the same path on the grid side.
Assisted-by: pi
* ui: make model information dialog full-screen on mobile
Matches the settings dialog pattern: full viewport below md,
calc-sized and capped at 60rem on desktop.
Assisted-by: pi
* ui: stack chat template row in model information dialog
Label above the block in a single full-width cell, so the template
gets the whole table width and its horizontal scroll is usable on
narrow screens.
Assisted-by: pi
* ui: scroll model information header with the content
The base dialog header is sticky; this dialog overrides it to
relative so the title and description scroll away with the body.
relative keeps the header as the close button's containing block.

* ui: replace literal comment text in sheet group snippet
A // line inside the Svelte snippet rendered as visible text; use an
HTML comment.
Assisted-by: pi
* ui: let indeterminate state win over checked in group checkboxes
The checkbox indicator snippet renders the check icon whenever
checked, so the mixed state never showed. Pass the checked prop
as false while indeterminate.
Assisted-by: pi
* ui: initialize only policy-enabled MCP servers for a flow
ensureInitialized accepts an optional server id set; the agentic
flow passes the servers its tool policy leaves usable, so servers
disabled for the conversation no longer get connected. Callers
without arguments keep the global behavior.
Assisted-by: pi
* ui: derive group checkbox state in useToolsPanel
Moves the mixed-state derivation out of the submenu and sheet
snippets into one getGroupCheckState accessor; the snippets just
consume checked and indeterminate.
Assisted-by: pi
* ui: gate /prompt command on the conversation tool policy
The slash command's availability now follows the same rule as the
agentic flow instead of the global capability check, so it disables
itself when the conversation's policy leaves no usable MCP server.
Assisted-by: pi
* ui: remove dead MCP prompt menu trigger chain
The /prompt slash command is the surviving trigger; the menu-button
path (onMcpPromptClick, hasMcpPromptsSupport, showMcpPromptButton,
the MCP_PROMPT attachment item and its unrendered item arrays) has
no consumer left. Message display for inserted prompts is untouched.
Assisted-by: pi
* ui: render dash for mixed-state group checkboxes
The accessor refactor dropped the checked-and-not-indeterminate
guard, so the category-on flag won and the dash never showed. The
tooltip keeps using the raw parent flag since clicking a mixed
group still disables it.
Assisted-by: pi
* ui: fix group checkbox sticking checked after disable
Clicking a mixed-state group box let bits-ui optimistically flip
its internal checked flag; the derived checked prop did not change
across the transition (both mixed and off map to checked=false),
so Svelte never applied the settled value and the check icon stuck
while the count already read 0/7.
Pass the parent flag as checked and the mix as indeterminate, so
every group toggle changes checked; render the dash on top of a
checked box for the mixed state.
Assisted-by: pi
* fix: UI for Model Information dialog
* ui: keep MCP connections stable across policy switches
ensureInitialized folds the policy into its config signature, so
alternating two conversations with different policies tore down and
reconnected every server with health checks included. Tool collection
already filters by the flow policy, so initialize every
settings-enabled server instead and never pass a policy into the MCP
config. The duplicated policy-server check becomes one accessor on
ConversationPreferences.
Assisted-by: pi
* ui: remove dead MCP resources menu trigger chain
Same shape as the earlier prompt trigger cleanup: nothing renders the
MCP resources menu button, and the only live entry into resource
browsing is Settings > MCP Servers plus the attachment resource
picker. Drop onMcpResourcesClick, hasMcpResourcesSupport,
MCP_RESOURCES_CLICK, the AttachmentItemVisibleWhen enum and
hasResourcesCapability; the resources display, browser and picker
components are untouched.
