## Summary
- Tighten `link_pattern_file_candidates` regex from `\(([^)]*)\)` to
`]\(([^)]*)\)` so only Markdown link syntax `[title](path)` triggers
path extraction from parentheses
- Prevents function call arguments like `do_work(file2)` from being
incorrectly resolved as file paths, which preempted LSP go-to-definition
Closes#48938
## Test plan
- [x] `cargo test -p editor hover_links` — all 12 tests pass
- [x] New unit tests verify: function calls don't extract arguments as
file candidates; Markdown links still extract correctly
