Jinwoo Hong 2c2d068b26 perf(usage): resolve each cwd's worktree once per scan (#21130)
* perf(usage): resolve each cwd's worktree once per scan

Codex and OpenCode attribution ran the worktree containment search for every
parsed event, so a cold scan cost events x worktrees. On 745 MB of real
rollouts (~20k events) that is 1.2s with 0 worktrees, 5.0s with 100, 12.8s
with 300 and 39.8s with 1000; a full corpus with hundreds of remembered
worktrees is where the STA-7724 reparse burned minutes of main-thread CPU.

A scan holds only a few hundred distinct cwds, so both scanners now build one
memoized resolver per scan and thread it through parsing instead of passing the
worktree list to every event.

* refactor(usage): make the worktree resolver own canonicalization

`createUsageWorktreeResolver` now takes raw worktree refs and canonicalizes
them itself, so each scanner has one entry point and neither keeps a private
`buildWorktreesWithCanonicalPaths` or `canonicalizePath`. The resolver unit
test counts comparisons through the same `areWorktreePathsEqual` mock the
scanner-level test uses instead of a property getter.
