[docs] Update documentation for features from 2026-06-03

[github-actions]

Summary

Two documentation-only updates to the gh-aw reference docs:

1. Repository Package Manifest — license field (repository-package-manifest-specification.md)
   A new optional license field (SPDX identifier string) has been documented in the aw.yml manifest spec.
   A new table row and dedicated sub-section §4.7 describe the field's purpose and accepted values.

2. Safe-Outputs Pull Requests — submit_pull_request_review wildcard target (safe-outputs-pull-requests.md)
   A clarifying note has been added explaining that when target: "*" is configured, agents must supply pull_request_number (and may optionally supply repo) in every submit_pull_request_review call.

Details

license field in aw.yml

• What: New optional field in the repository package manifest spec.
• Type: SPDX identifier string (e.g. "MIT", "Apache-2.0").
• Location in spec: Added to the fields summary table and introduced as a new §4.7 section.
• Impact: Purely additive; no existing manifests are affected.

submit_pull_request_review with target: "*"

• What: Clarification note for agents using the wildcard review target.
• Why: When target: "*" is set, the framework cannot infer which pull request to act on, so callers must explicitly provide pull_request_number; repo is optional but available.
• Impact: No behaviour change — this documents existing runtime requirements that were previously implicit.

---

Risk Assessment

• No code changes — documentation only.
• No breaking changes.
• Both additions are additive clarifications / new spec entries; existing configurations and agent implementations are unaffected.
