1.1.0

Agent Layer Improvements (milestone 18)

• Removed every pinned model: opus from the plugin — the three agents and the two skills that carried it — so dispatched agents and skills now inherit the session's model instead of forcing Opus.
• Recolored the three agents red (complete-task), yellow (answer-open-question-with-recommendation), and blue (recommend-open-question) so no two share a color and all three stay distinguishable on a grayscale display.
• Hardened /recommend-all-open-questions: the recommend-open-question agent now returns FAILED: <reason> on failure, and the sweep shape-checks every return before embedding, skipping a failed or malformed one (block left untouched, skipped questions reported) instead of splicing prose into requirements.md as XML.
• Orchestrators now address their agents by namespaced registry name (cairn:complete-task, cairn:recommend-open-question, cairn:answer-open-question-with-recommendation), and the recommend sweep passes the milestone directory to its agent so it grounds itself in that milestone's requirements.md directly.
• Made a failed or interrupted complete-task run resumable: partial work is left uncommitted in the tree and the next run continues from it rather than promising an untouched tree it could never guarantee.
• The two file-editing agents now stage their own change set path-scoped and return a bare DONE/FAILED: <reason>; /complete-all-tasks and /answer-all-open-questions-with-recommendation commit that staged index, keeping one commit per task or answer.
• Answer recording now folds the decision into ## Decisions before removing the <open-question> block, so an interruption between the two edits can no longer silently lose a question.
• The Antigravity build now rewrites every ${CLAUDE_PLUGIN_ROOT}/shared/<name>.md reference to .agents/plugins/cairn/shared/<name>.md, so the generated tree's shared-procedure references resolve under Antigravity instead of pointing nowhere.
