Task commands form a cohesive feature set for managing session tasks.

- t: list tasks with optional status filter
- t a: add multiple tasks (validates title/description pairs)
- t u: update task status, title, or description (requires reason for
  content changes and cancel/fail)
- All commands print plan and provide contextual next steps

- g: show goal with full plan
- g s: set goal (requires title and description)
- g u: update goal (requires reason and at least one change)
- All commands print plan and provide contextual next steps

Introduces event, goal, and task storage subsystems built on Badger:

- event: append-only log with typed payloads for state changes
- goal: CRUD operations for session goals with event tracking
- task: full lifecycle management with status indexing
- testutil: helpers for deterministic test clocks and databases
- timeutil: clock abstraction for testability

All packages include comprehensive test coverage.

Fix View transaction to return nil on success instead of ctx.Err(),
which
caused spurious failures when a context deadline was set but the
operation
completed successfully before expiration.

Improve configuration defaults for CLI durability:
- Default SyncWrites to true to ensure planning state persists across
  crashes
- Use os.UserConfigDir() instead of custom platform logic for better
cross-platform config directory handling

Code cleanup:
- Remove redundant txn.Discard() after successful commit
- Rename suffixTasks to suffixTask for singular/plural consistency
- Fix KeyString doc to correctly state it allocates
- Remove unused ctx assignment in View

Had a combo of Claude Code/Sonnet 4.5 and Amp/GPT-5 (Oracle) write one
schema each, then used CC and Crush/GPT-5 (high) to polish up CC's
version. Then I presented both schemas to CC and Crush/GPT-5 and asked
which they prefer. Both suggested copying some choice ideas from CC's
schema, but instead adopting Amp's schema overall.
