* fix(gstack-slug): sanitize cached slug before eval
The compute and fallback paths filter slug output to [a-zA-Z0-9._-], but a
value read straight from ~/.gstack/slug-cache was echoed into eval output
unsanitized. A locally-planted cache file could inject shell into
eval "$(gstack-slug)". Re-sanitize on every path so the invariant the file
header promises actually holds, and heal a poisoned cache on the next write.

* fix(telemetry): accurate consent copy + JSON-safe repo basename
The telemetry consent prompt promised "no repo names" while the preamble
epilogue records the repo basename in the local skill-usage.jsonl. It is
already stripped before any remote upload, so it never left the machine, but
the copy was unqualified. Reword it to state repo name is local-only and
stripped before upload.
Also sanitize the basename to [a-zA-Z0-9._-] before it goes into the
hand-built JSON, so a repo directory name containing quotes or newlines can
neither break the JSON nor leak a fragment past the regex stripper.

* chore(docs): regenerate SKILL.md + ship goldens for telemetry change
Generated output of the preceding resolver change: the corrected consent copy
and sanitized repo basename now appear in every skill preamble. Golden ship
fixtures refreshed to match.

* test(telemetry): enforce no-repo-identity-egress invariant
Pins the contract that repo/branch identity in the synced skill-usage.jsonl is
stripped before the remote POST. Three checks: a floor (the three known fields),
coverage (every repo/branch field a producer writes into skill-usage.jsonl is
stripped, so a future producer rename can't silently leak), and behavior (runs
the actual sed strip expressions over a sample event). Scoped to the synced
file, so the local-only timeline branch field is correctly excluded.

* test(gstack-slug): regression test for cached-slug eval injection
Proves a poisoned ~/.gstack/slug-cache file cannot inject shell metacharacters
into gstack-slug output (the value consumed by eval). Verified red when the
cache-read sanitization is removed.
