Will Miao aa630bf85b perf(services): skip per-file realpath work in cache reconciliation
A no-change Refresh still computed os.path.realpath for every model file
in the library and for every cached entry. Both values are only ever
consulted when a discovered file is missing from the cache, so on a
50k-file library they cost ~1.3s and ~0.6s while being used zero times.

- Compute the per-file realpath only after the exact cache match fails
- Build the physical-path alias map lazily on the first miss; the
  cross-run alias guard (overlapping roots / symlink layout changes)
  still keeps the cached entry instead of a delete + re-add, which would
  re-read metadata and re-hash the whole library
- Snapshot get_model_roots() once for the new-file pass instead of
  re-reading it for every added file
- Run the duplicate-path integrity pass only when the snapshot already
  contained duplicates or files were appended; a clean, unchanged cache
  has nothing to clean. Duplicates can only be introduced by external
  code rewriting raw_data or by this pass's own appends.

Zero-change reconcile drops from ~1400ms to ~120ms on 50k files, and an
alias flip still re-processes 0 files (#1108 investigation).
