chore: migrate from opencode to trellis 0.5.0-rc.6

- Remove legacy .opencode/ directory and configuration - Update .trellis/ to v0.5.0-rc.6 structure - Refactor scripts: modularize common/, remove multi_agent/ - Add new common modules: git.py, io.py, log.py, types.py, etc. - Update workflow.md and AGENTS.md - Archive completed migration tasks

+"""Trellis per-turn breadcrumb hook (UserPromptSubmit / BeforeAgent equivalent).
+
+Runs on every user prompt. Resolves the active task through Trellis'
+session-aware active task resolver and emits a short <workflow-state>
+block reminding the main AI what task is active and its expected flow.
+
+The emitted ``hookEventName`` field is platform-aware: most hosts expect
+``UserPromptSubmit`` (Claude Code naming, also accepted by Cursor / Qoder /
+CodeBuddy / Droid / Codex / Copilot wiring), but Gemini CLI 0.40.x renamed
+its per-turn event to ``BeforeAgent`` and its schema validator rejects the
+legacy name. ``_detect_platform`` picks the right value at runtime.
+Breadcrumb text is pulled exclusively from workflow.md
+[workflow-state:STATUS] tag blocks — workflow.md is the single source of
+truth. There are no fallback dicts in this script: when workflow.md is
+missing or a tag is absent, the breadcrumb degrades to a generic
+"Refer to workflow.md for current step." line so users see (and fix)
+the broken state instead of the hook silently masking it.
+
+Shared across all hook-capable platforms (Claude, Cursor, Codex, Qoder,
+CodeBuddy, Droid, Gemini, Copilot). Kiro is not wired (no per-turn
+hook entry point). Written to each platform's hooks directory via
+writeSharedHooks() at init time.
+
+Silent exit 0 cases (no output):
+  - No .trellis/ directory found (not a Trellis project)
+  - task.json malformed or missing status
