v0.5.0-rc.3

Patches Gemini CLI 0.40.x template compatibility (#224). No new migrations.

Bug Fixes

Three changes to trellis init --gemini output:

File	Change
`.gemini/agents/trellis-{check,implement,research}.md`	Drop `tools:` line — sub-agent inherits parent tools
`.gemini/settings.json`	Hook event `UserPromptSubmit` → `BeforeAgent`
Shared skills destination	`.gemini/skills/` → `.agents/skills/`

Existing Gemini installs: re-run trellis init --gemini or delete .gemini/skills/ manually.

Branches via _detect_platform():

hook_event_name = (
    "BeforeAgent" if _detect_platform(data) == "gemini" else "UserPromptSubmit"
)

Narrowed from any .agents/skills/ hash entry to:

keys.some((k) => k === '.agents/skills/trellis-continue/SKILL.md') ||
  keys.some((k) => k === '.agents/skills/trellis-finish-work/SKILL.md');

Only Codex writes those two files. The previous broad heuristic auto-installed Codex on trellis update for Gemini-only projects.

npm install -g @mindfoldhq/trellis@rc
trellis update

Projects on 0.5 (beta or earlier rc) run trellis update. From 0.4.x: trellis update --migrate.
