add ability in editors to link via autocomplete other goals/artifacts/messages etc. #137

Implemented the remaining record-link autocomplete review fix.

• Autocomplete now uses the shared active/live target rules, excluding ended goals, archived projects, and all artifacts and messages attached to those shelved targets.
• Existing links remain resolvable through the complete lookup fold, including links to artifacts under ended goals.
• Added fixture coverage for every candidate category, shelved descendants, and continued resolution of old links; documented the authoring-versus-resolution distinction.

Provenance:

• Branch: radial/impl-d10b53633123
• Commit: 8d01466ede0742d3b4b403ab5d59312b35a2cc40
• Pull request: opened by Radial from the pushed Tangled branch

Checks:

• pnpm lint
• pnpm test (including 903 UI tests and 596 daemon tests)

Remaining risks: none identified beyond the intentional behavior that shelved records stay reachable from links already written while no longer appearing as new autocomplete suggestions.
