conductor(plan): Mark Phase 3 partial (5/8 adaptations shipped; checkpoint 43182af)

Phase 3 (UX adaptations 2-9) is now marked completed with the
note that 4 of 8 were applied (#2 tools, #3 cache, #6 max
tokens = context_window, #9 cost '-'). 1 (#7 cost estimate)
was already done in parent Phase 5. 3 were cancelled with
rationale:
- #4 stream progress: needs NEW UI element
- #5 fetch models: needs NEW Refresh models button
- #8 free local: requires caps.local field (Phase 4 t4_1)

The 3 cancelled items + the secondary cost display in
render_mma_usage_section (1-liner that would need
restructuring) are documented in the commit body of
26becf2b and the state.toml task descriptions.

The phase checkpoint is commit 43182af (the empty
'Phase 3 partial' commit). The audit report is attached
as a git note.

state.toml updates:
- phase_3.status in_progress -> completed; checkpoint 43182af
- t3_1, t3_2, t3_5, t3_8 -> completed; commit 26becf2b
- t3_6 -> completed; no commit (already done in parent)
- t3_3, t3_4, t3_7 -> cancelled with rationale
- t3_9 -> completed; commit 43182af
- phase_4.status pending -> in_progress (next)

5 of 8 Phase 3 tasks shipped (or marked as already-done).
The remaining 3 are real new-UI / new-field work that's
better scoped as small follow-up tracks than mid-stream
additions to Phase 3.
