Session Cartographer 0.7.1

Session Cartographer 0.7.1

A follow-up to 0.7.0. The attribution migration under-repaired: events recorded from
a subdirectory of a worktree were skipped.

Who needs this

Anyone who ran the 0.7.0 migration. Re-run it — the pass is idempotent and picks up
only what was missed:

node scripts/migrate-project-attribution.js            # dry run
node scripts/migrate-project-attribution.js --apply

If the dry run reports 0 event(s) would be repointed, you were unaffected and there
is nothing to do.

What was wrong

The migration repointed a record only when its project equalled basename(cwd). The
hook it repairs, though, derived the project from git rev-parse --show-toplevel, which
returns the worktree root no matter how deep the working directory was. An event
recorded in …/worktrees/confident-yalow-e1cdc6/apps/capacitor/android therefore carried
confident-yalow-e1cdc6 as its project alongside a much deeper cwd, and the check
skipped it.

The signature now also accepts a project matching the basename of the cwd's own
toplevel. On the development corpus that recovered 18 further events across 2 phantom
projects.

Nothing else changed, and the 0.7.0 write-time fix was never affected — new events were
always attributed correctly regardless of directory depth.
