chore(worktree): put worktrees under .claude and carry the overrides into them

[anilcancakir]

What

• .gitignore: ignore .claude/worktrees/ (only that subdirectory; the rules under .claude/ stay tracked)
• .worktreeinclude: new, copies pubspec_overrides.yaml into every worktree Claude Code creates

Why

Worktrees were opened beside the checkout as <repo>-<slug>, so they landed in the workspace directory next to the real repositories, and Claude Code's EnterWorktree could not be used at all: it writes to a fixed .claude/worktrees/<slug>.

Moving them inside exposes a problem the old layout hid. pubspec_overrides.yaml is gitignored, so a worktree never receives it, and the absence is silent rather than loud: the siblings resolve from pub.dev, flutter pub get succeeds, and the suite passes against the PUBLISHED packages while the diff under review is of the local ones. An unreleased sibling API is where that bites.

For the copy to be correct the local file needs ABSOLUTE paths, since a relative ../magic resolves to .claude/worktrees/magic from inside a worktree. That file is machine-local and not committed, so this PR cannot carry it; the requirement is documented in .worktreeinclude.

Testing

The pattern was proven end to end on fluttersdk/magic_starter#124 first: probe worktree opened under the new path, pubspec_overrides.yaml confirmed absent, copied in, flutter pub get resolved and package_config.json pointed at the local checkouts. Here I verified that every rewritten absolute path resolves to a real package directory and that flutter pub get still succeeds.

No Dart, YAML or lib/ file is touched, so analyze, format and test have nothing to say about this diff.

Summary by CodeRabbit

• Chores
  • Improved isolated development workspace setup by preserving local package configuration across generated worktrees.
  • Added safeguards to keep temporary parallel-workspace files out of version control.
• Documentation
  • Clarified how workspace configuration is copied and how cleanup commands affect temporary worktrees, supporting more predictable development workflows.

Two config files, both correct: the ignore rule scopes exactly to .claude/worktrees/ without shadowing the tracked rules, and nothing else in the repo is affected.

No findings.

What I checked and why I believe it is safe:

• The narrow-ignore claim holds. git check-ignore -v matches .claude/worktrees/probe/lib/bad.dart on .gitignore:60 and does not match .claude/rules/tests.md, so the tracked rules under .claude/ stay tracked. git status --short is clean at head.
• Nothing leaks into the published archive. .pubignore replaces .gitignore at publish time and does not list .worktreeinclude, which looked like a gap, but dart pub publish --dry-run shows the file is not in the manifest (no root dotfiles are), and .claude/ is already excluded there, so worktrees cannot inflate the archive either. Archive size unchanged at 1 MB, 0 warnings.
• No tooling traverses the new directory. tool/check-docs.py is rooted at doc/, example/lib/pages, example/lib/routes.dart and a fixed extra-page list; tool/coverage.sh runs flutter test, which reads test/ only. analysis_options.yaml does not exclude .claude/, but both dart analyze and dart format skip dot-prefixed directories, so a nested worktree does not get double-analysed. I could not prove that last point by experiment - creating a probe file under .claude/worktrees/ was not permitted in this run - so treat it as reasoned rather than observed.

Tests

None, and none are warranted: the diff is .gitignore plus a new .worktreeinclude, with no Dart, YAML or lib/ change, so the CHANGELOG.md and five-surface sync obligations in CLAUDE.md do not trigger.

Checks I ran

• git check-ignore -v .claude/worktrees/probe/lib/bad.dart .claude/rules/tests.md pubspec_overrides.yaml - matched lines 60 and 55; the rules file correctly did not match.
• git status --short - clean.
• dart pub publish --dry-run - resolved, 0 warnings, 1 MB archive, .worktreeinclude absent from the file list.
• Read .pubignore, analysis_options.yaml, tool/check-docs.py, tool/coverage.sh, .lycheeignore to confirm no path assumptions break.
• No linter, analyzer or test run: this diff contains no code they read.

Since my last review the only change is four added comment lines in .gitignore documenting the git clean -xdf hazard; the ignore behaviour is unchanged and still correctly scoped, with one stray character to tidy.

Minor

.gitignore:58 — the paragraph break lost its #: the line reads # under it are part of the repository.# instead of ending the sentence and starting a bare # separator line before # They sit inside.... Purely cosmetic in a comment - git ignores it either way - but it reads as a typo. (maintainability)

Tests

None, and none are warranted: the new commit adds only comment text to .gitignore, so the CHANGELOG.md and five-surface sync obligations in CLAUDE.md still do not trigger.

Checks I ran

• git check-ignore -v .claude/worktrees/probe/lib/bad.dart .claude/rules/tests.md - matched .gitignore:64 for the worktree path only; .claude/rules/tests.md did not match, so the tracked rules stay tracked.
• git status --short - clean at head 0e52582.
• Read .gitignore:50-64 to confirm the added lines are all comments and the pattern itself is byte-identical to the previously reviewed version.
• No linter, analyzer or test run: this increment contains no code they read.

Since my last review the only change is comment text in .gitignore: the stray # I flagged is gone and the git clean note is now corrected to say -xdf skips a nested worktree while -xdff does not. Ignore behaviour is byte-identical and still correctly scoped.

No findings.

The corrected claim reads right to me: git's clean skips an untracked directory it identifies as a non-bare repository, and that check resolves a .git gitfile as well as a .git directory, which is exactly the linked-worktree case, so -xdf prints "Skipping repository" and -xdff overrides it. I could not demonstrate this by experiment in this run - creating a probe worktree was not permitted - so treat it as reasoned rather than observed.

Tests

None, and none are warranted: this increment changes only comment lines in .gitignore, so the CHANGELOG.md and five-surface sync obligations in CLAUDE.md still do not trigger.

Checks I ran

• git check-ignore -v .claude/worktrees/probe/lib/bad.dart .claude/rules/tests.md - matched .gitignore:66 for the worktree path only; the tracked rules file did not match.
• git status --short - clean at head 69cc569.
• Read .gitignore:50-66 to confirm the added lines are all comments and the pattern itself is unchanged from the previously reviewed version.
• No linter, analyzer or test run: this increment contains no code they read.

[anilcancakir]

Tested this rather than reasoning from it, and the claim does not hold: EnterWorktree does process .worktreeinclude.

Ran EnterWorktree in a sibling repository whose .worktreeinclude lists three files, then checked the created worktree:

=== cwd ===
.../.claude/worktrees/probe-worktreeinclude
=== did .worktreeinclude get processed? ===
  pubspec_overrides.yaml = COPIED
  backend/.env          = COPIED
  .artisan/plugins.json = COPIED

All three arrived. The worktree and its branch were removed afterwards.

Where the confusion comes from is real though, and worth recording: the official page lists the honouring paths as "--worktree worktrees, subagent worktrees, and parallel sessions in the desktop app" and does not name EnterWorktree among them (https://code.claude.com/docs/en/worktrees). That list reads as exhaustive and is not, at least as of today. The third-party source behind the "documented inconsistency" phrasing asserts the opposite of what the tool actually does here.

The one caveat the docs are right about is already in the file: a WorktreeCreate hook replaces the default git logic, and then nothing here is copied. This repository has no such hook.

Leaving the line as written.
