fix git pr metadata tmpfile cleanup

F-01 (HIGH): issue-edit.sh and issue-assign.sh used string interpolation
+ eval to build CLI commands. Replace all eval sites with Bash arrays so
user-supplied values (title, body, labels) are never shell-expanded.
For the Gitea path, replace get_gitea_repo_args() (which emits %q-escaped
strings designed for eval) with get_repo_slug() + get_gitea_login() so
repo/login are passed as properly-quoted array elements.

F-07 (MED): milestone-create.sh built the GitHub API JSON payload by
string interpolation — a title containing " or $ broke the JSON. Rebuild
with jq -n --arg so all values are safely serialised. Optional description
key is omitted when empty, preserving existing behaviour.

F-13 (LOW): pr-metadata.sh created a mktemp tmpfile inside
curl_gitea_pull() but only removed it in success paths. Add
trap 'rm -f "$body_file"' EXIT immediately after mktemp so early-exit
paths (set -e, SIGINT) also clean up.

+## 2026-06-18 — PR #549 functional blocker remediation
+
+### Assignment
+
+Coordinator `mos-claude` assigned remediation for PR #549: fix `packages/mosaic/framework/tools/git/pr-metadata.sh` tmpfile cleanup where an `EXIT` trap references function-local `body_file` after the function returns inside `RAW=$(...)`, producing `body_file: unbound variable` on the authenticated success path and failing to clean up safely on early `set -e` exits.
+
+### Plan
+
+1. Add a non-vacuous Gitea test that exercises `curl_gitea_pull` with stubbed `curl` and `GITEA_TOKEN` instead of `MOSAIC_GITEA_PR_METADATA_RAW_FILE`.
+2. Prove the new test is RED against the current PR head.
+3. Replace the function-local `EXIT` cleanup with robust function-scoped tmpfile cleanup.
+4. Re-run targeted tests, `bash -n`, and review gates; commit and push branch only. Do not merge.
+
+### Constraints / assumptions
+
+- Do not modify prior injection/JSON fixes in `issue-edit`, `issue-assign`, or `milestone-create`.
+- Worker role: do not modify `docs/TASKS.md`; orchestrator remains the single writer.
+- Budget: no explicit token cap provided; keep scope to shell wrapper + targeted regression harness.
+
+### Remediation results
+
+- Rebased `fix/tooling-eval-injection-jq-json` onto `origin/main`; branch was already current.
+- Added a curl-stub regression path that does not use `MOSAIC_GITEA_PR_METADATA_RAW_FILE`, so it exercises `curl_gitea_pull` and its temp body file.
+- RED evidence: copied the new harness next to the pre-fix `HEAD` version of `pr-metadata.sh`; `MOSAIC_TEST_WORK_DIR=$PWD/.mosaic-test-work/pr-metadata-red-work .../test-pr-metadata-gitea.sh` failed with `body_file: unbound variable` on the curl success path.
+- Fix: replaced `EXIT` temp-file cleanup with a `RETURN`-scoped cleanup function that removes the body file while the function-local variable is still in scope, preserves the original return status, and clears the `RETURN` trap.
+- GREEN evidence:
+  - `MOSAIC_TEST_WORK_DIR=$PWD/.mosaic-test-work/pr-metadata-gitea-current packages/mosaic/framework/tools/git/test-pr-metadata-gitea.sh` passed.
+  - `bash -n packages/mosaic/framework/tools/git/pr-metadata.sh packages/mosaic/framework/tools/git/test-pr-metadata-gitea.sh` passed.
+  - `shellcheck -x -P . -e SC1090 packages/mosaic/framework/tools/git/pr-metadata.sh packages/mosaic/framework/tools/git/test-pr-metadata-gitea.sh` passed.
+
+### Review remediation
+
+- Codex review returned one should-fix: the early-exit test used `chmod 000`, which is not root-safe in container CI.
+- Remediation: changed the stubbed 2xx/cat-failure mode to replace the curl output with a broken symlink, which fails deterministically even as root and still validates cleanup via `rm -f -- "$body_file"`.
+
+### Second review remediation
+
+- Codex review found the 2xx `cat "$body_file"` read could be masked under command substitution semantics because the branch returned 0 unconditionally.
+- Remediation: both authenticated 2xx branches now use `cat "$body_file" || return $?` before returning success.
+- Strengthened the broken-symlink test to require the body-read failure and reject the later `Gitea API returned non-JSON` parse-failure path, so the test verifies the helper-level failure propagation rather than eventual downstream failure.
+
+### Final review gate
+
+- Codex review after remediation: approved (`0 blockers, 0 should-fix, 0 suggestions`).
