Tom Boucher b9adedbc86 fix(#3151): stop emitting effort: into skill frontmatter (cache invalidation) (#3425) ...

Claude Code applies SKILL.md effort: as output_config.effort; any change from
the session baseline invalidates the prompt cache at BOTH scope boundaries
(entry + exit, the latter often machine-fired via subagent-completion
notification). The reporter's owned measurement confirms it: /gsd-progress
(effort:low) in a medium session → cache_creation 63,404 (entry) + 18,589
(exit), while a no-effort skill shows none. ~76% of invocations paid in full.

Fix (trek-e AC#2/AC#4): convertClaudeCommandToClaudeSkill no longer emits
effort: into Claude-runtime skill frontmatter (src/runtime-artifact-conversion.cts
+ duplicated bin/install.js). normalizeClaudeSkillEffort removed (dead). The six
declaring skills (plan-phase/execute-phase/autonomous/next/progress/stats) no
longer carry effort. Source command files keep effort (input, used elsewhere);
the separate agent-effort surface (#3160) is untouched.

Tests: install-runtime-artifacts #769 block flipped to assert effort is ABSENT
from installed SKILL.md + converter output (the AC#4 behavioral coverage).
