fix(explore): reliably pin extension-less kebab-case file basenames in queries

Browse Source 
Previously, naming a kebab-case file without its extension (e.g., `background-image-table` vs. `background-image-table.tsx`) in a `codegraph_explore` query would shred the name into fragments (`background`, `image`, `table`), admitting irrelevant sibling files and crowding out the intended target.

This change introduces a new resolution pass in `extractQueryPaths` specifically for extension-less kebab basenames. Queries now accurately identify and pin these files. Unresolved hyphenated prose (e.g., `cross-call`) is left in the query for FTS without being flagged as an unknown path. Resolution prioritizes explicit slashed/dotted paths and respects an ambiguity budget for common stems to prevent over-pinning.

### Fixes
- Naming a file by its path in a `codegraph_explore` query now works reliably: the path is resolved against the index and that file is guaranteed a place at the top of the answer. Previously the path was broken into fragments — bracketed route segments like SvelteKit's `[id]` made this worst — and pieces like `page` or `runs` matched every sibling file, so the file you actually named could be crowded out of the answer entirely. A path that doesn't match any indexed file is now called out instead of silently ignored.
- Naming a kebab-case file **without its extension** in a `codegraph_explore` query — `background-image-table` rather than `background-image-table.tsx`, the way import paths and prose spell it — now returns that exact file too. Previously the name was split at the hyphens, and in a kebab-cased frontend those pieces (`background`, `image`, `table`) are among the most common words in the codebase, so look-alike sibling files filled the answer while the named file never appeared. Hyphenated words that don't name an indexed file, like "cross-call" or "non-blocking", are left alone.
- Plainly-worded `codegraph_explore` questions now find camelCase code: a query like "auto-scroll to bottom" can reach a function named `scrollFeedToBottom`, because query words are matched against the words inside identifiers, not just whole names.
- Variables and constants now count when `codegraph_explore` picks its starting symbols, so state held in plain variables — `$state`-style variables in Svelte, for example — no longer gets overlooked.
- C, C++, Objective-C and Rust unions are now indexed as first-class `union` nodes. A `union` declaration previously produced no symbol at all, so it never appeared in search or `codegraph_explore`, and anything attached to it disappeared with it — in Rust, every `impl SomeTrait for MyUnion` lost its edge, the methods from that impl were left pointing at a type the graph did not contain, and asking which types implement a trait quietly skipped the union ones. A union-shaped dispatch table in C now resolves its function pointers like a struct-shaped one. A `typedef union { … } Name;` in C keeps the typedef's name and is no longer mistaken for a plain type alias. Thanks @ctype-lab. Re-index after upgrading to pick up unions in existing projects.
