fix(build): improve static path generation performance and fix parameter collisions (#81254)
## Summary
• **Performance**: Replace O(n²) parameter deduplication with O(n)
Map-based approach
• **Architecture**: Rewrite `assignErrorIfEmpty` using [Trie data
structure](https://en.wikipedia.org/wiki/Trie)
• **Testing**: Add comprehensive test coverage for edge cases including
parameter collisions and complex route hierarchies
## Technical Details
### Performance Optimization
- **Before**: O(n²) nested loops comparing each parameter combination
against all previous ones
- **After**: O(n) Map-based deduplication using unique string keys for
each parameter combination
- **Impact**: Significant performance improvement for routes with many
parameter combinations
### Trie-Based Route Analysis
Replaces linear route comparison with efficient Trie data structure:
- **Nodes**: Represent unique parameter combinations
- **Edges**: Represent parameter values with collision-safe keys
- **Algorithm**: [DFS
traversal](https://en.wikipedia.org/wiki/Depth-first_search) determines
`throwOnEmptyStaticShell` based on child relationships
**Example**: For routes `/blog/[slug]` and `/blog/first-post`:
- Trie identifies `/blog/[slug]` as parent to concrete route
`/blog/first-post`
- Sets `throwOnEmptyStaticShell = false` for parent, `true` for concrete
route
