kshitij 4fa8d7bb67 fix(tools): staleness + tracking-parity fixes for the not-found cache
Review follow-ups on the #25387 salvage:

1. CRITICAL: a cached miss survived out-of-band file creation (terminal
   command, external process) for the full 60s TTL — breaking the common
   agent pattern 'check for file -> create it -> read it' (live-repro'd).
   Serve-side existence guard: one ~free stat before serving a cached
   miss; if the path now exists the entry is evicted and the real read
   runs. Also fixes the search-root variant (write under a cached-missing
   directory). Both mutation-checked.

2. notify_other_tool_call now clears the task's not_found entries too
   (belt: the dispatcher calls it for every non-read tool).

3. Tracking parity: the record sites no longer early-return. On upstream,
   error results flow through consecutive-loop detection and dedup
   bookkeeping; short-circuiting skipped that and broke
   TestDedupInvalidationTaskResolution when preceded by
   TestSilentFileMisplacementE2E (bisected: the early return at the
   read record site was the trigger). Recording is now
   side-effect-identical to upstream; serving from the cache remains the
   optimization. Also reuse the already-computed _resolved instead of
   resolving a second time.
