feat(compaction): add dynamic context pruning as recovery stage

Implements DCP-style pruning strategies inspired by opencode-dynamic-context-pruning plugin:

- Deduplication: removes duplicate tool calls (same tool + args)
- Supersede writes: prunes write inputs when file subsequently read
- Purge errors: removes old error tool inputs after N turns

Integration:
- Added as Stage 2.5 in compaction pipeline (after truncation, before summarize)
- Configurable via experimental.dynamic_context_pruning
- Opt-in by default (experimental feature)
- Protected tools list prevents pruning critical tools

Configuration:
- Turn protection (default: 3 turns)
- Per-strategy enable/disable
- Aggressive/conservative modes for supersede writes
- Configurable error purge threshold (default: 5 turns)
- Toast notifications (off/minimal/detailed)

Testing:
- Added unit tests for deduplication signature creation
- Type check passes
- Schema regenerated

Closes #271
