feat(todo): add blocked and dropped task statuses

Linked issue

Closes #1814 (status:approved).
Closes #1820 (status:approved).

PR type

• New feature (type:feature)

Summary

• Add dropped (✕): a terminal status for tasks a change of plan made obsolete. It never counts as open, so a list of only done and dropped finishes, clears, and leaves the prompt. It leaves the done of total count, renders dim without strikethrough, and folds into ✕ N dropped in long lists. cancelled, canceled, and abandoned are accepted as aliases.
• Add blocked (⊘, warning role): open but not actionable. It requires a note (blocked needs a note naming what it waits for), renders that note next to the title, never makes the list stale on its own, and the collapsed card skips it when choosing the next task.
• ODD guidance in assets/orchestrator-memory.md covers projecting both from the feature document: dropped tasks get a ## Log reason and never satisfy their dependents; blocked tasks name their unblocking condition; an in-list prerequisite is ordering, not blocking.

Review path

Area	Change
lib/shell-todo.ts	New statuses, aliases, note rule, open/stale semantics, card rendering, prompt rules line.
extensions/gentle-todo.ts	Tool schema enums, note description, and two prompt guidelines.
assets/orchestrator-memory.md	Pi-only todo projection guidance (not part of the gentle-ai routing canon, which is cross-runtime).
docs/gentle-shell.md	Gentle Todo section documents the five statuses.
Tests	One test per rule in shell-todo, extension lifecycle and schema in gentle-todo, guidance in odd-integration.

TodoSummary keeps its shape; open now excludes dropped tasks. Herdr only reads in_progress titles and is unaffected.

Verification

• RED first: 7 new library tests, the schema test, and the ODD guidance test failed before the change; all pass after it.
• node --experimental-strip-types --test tests/shell-todo.test.ts tests/gentle-todo.test.ts: 40 passed.
• Contract tests (odd-integration, odd-routing-contract, task-size-routing-contract, orchestrator-budget, artifact-language, odd-routing-canonical-ratchet): 75 passed.
• npm test: 4,979 passed, 34 skipped, 0 failed; provider-contract and runtime harness passed (run before the final asset edit, whose contract tests were rerun above).
• npm run typecheck: no regressions. node scripts/verify-package-files.mjs and git diff --check passed.

Summary by CodeRabbit

• New Features

  • Todo lists now support blocked tasks, which require a note explaining what they’re waiting on, and dropped tasks for work that will not be completed.
  • Blocked tasks remain visible without making a list stale. Dropped tasks are treated as finished but do not count as done.
  • Todo guidance now distinguishes external blockers from task prerequisites and explains how to resume or drop tasks.

• Documentation

  • Updated task status descriptions and behavior, including accepted aliases for dropped tasks.
