v0.47.2

v0.47.2

Patch release: a wave of correctness and hot-path fixes from an automated
verify-fix loop, plus URL-reading and PATH improvements.

Data-integrity fixes

• apply_patch no longer corrupts CRLF files. Updating a file with Windows
  (CRLF) line endings previously wrote mixed endings (the changed line came
  back LF among CRLF lines). Patches now preserve the file's dominant line
  ending.
• inline refactor preserves operator precedence. Inlining twice(1 + 2)
  where twice(x) => x * 2 produced 1 + 2 * 2 (wrong: 5 instead of 6).
  Non-atomic arguments are now parenthesized.
• Python import aliases are no longer dropped. Removing one name from
  from m import a, b as c (or import a, b as c) could delete the whole
  statement including the aliased sibling. Aliases are now modeled and
  preserved.

Reliability fixes

• Fixed a health-probe deadlock under the daemon. A health check could
  deadlock against a starting background worker (lock-order cycle), stalling
  the probe until the supervisor restarted the module. Health checks now
  never wait on worker startup.

• extract_function no longer drops variables. Extracting a range that
  declared multiple variables used later kept only the first and silently
  deleted the rest (code that crashed at runtime). Multiple live-out
  variables now return together (object destructuring in TS/JS, tuples in
  Python), and unsupported shapes are rejected with a clear error instead of
  emitting broken code.

• File edits no longer rewrite the whole undo history in the database.
  Each edit re-wrote every retained undo entry (~41 SQL statements at default
  depth); appends now write only the delta.

• bash_watch no longer reports fabricated matches. stdout and stderr were
  concatenated before pattern scanning, so a pattern could "match" across the
  seam (stdout ERR + stderr OR = ERROR). Streams are now scanned
  independently, and matches report which stream they came from.

• bash wait: true polling no longer re-reads output 10×/second. Long
  foreground waits stopped doing redundant per-poll output reads under the task
  lock.

• Orphaned auto-update locks self-heal. A crashed process could leave a
  stale lock that permanently disabled update checks; dead/stale locks are now
  reclaimed.

• Warm symbol lookups skip re-hashing unchanged files (zoom/outline/rank-0
  search), and the LSP diagnostics store is indexed by file so watcher
  invalidation no longer scans every entry.

URL reading

• GitHub file links just work. aft_outline / aft_zoom on a
  github.com/…/blob/… URL now fetch the raw file content instead of the web
  page shell (GitLab -/blob/ too).
• Heading lookups tolerate real-world headings. Zooming a documentation
  heading now matches when you pass the human text, even if the outline shows a
  numeric prefix (12.1.5 …), a markdown link label, an emoji, or an anchor
  slug (#http_flow / http-flow).
• Paths and targets can be given as file:// URLs.

Shell PATH

• bash finds tools installed via your shell rc. The login-shell PATH probe
  now sources interactive rc files (zsh .zshrc), so binaries on a PATH you
  export there (e.g. ~/.opencode/bin) resolve in bash tasks.
