ui: re-enable advanced-mode ambient assistance (ADR-0022 Amendment 1)

Browse Source 
Advanced-mode hinting + completion-preview were dead: render_hint_panel
returned None for advanced mode (stale ADR-0022 §12 gate, predating the
SQL grammar) and the hint resolver/ambient_hint never threaded Mode, so a
SQL statement was gated as "this is SQL". The unified walker (ADR-0030/
0031/0032) speaks SQL, so this lifts the gate.

- ambient_hint_in_mode + hint_resolution_at_input_in_mode +
  expected_for_hint_snapshot(mode); candidate/diagnostic/parse sub-calls
  run in the active mode.
- render_hint_panel calls ambient for all modes; one-shot `:` sigil
  stripped (strip_one_shot_prefix) so `: sel` hints `select`.
- ADR-0022 Amendment 1 + README index.

Found by manual advanced-mode testing; Phase 2 marked SQL hint/completion
green at the engine layer but never exercised the UI. App-level render
test (advanced_mode_hint_panel_surfaces_sql_candidates) + ambient-layer
regression locks. 1466 baseline green.

- [ADR-0022 — Ambient typing assistance: colour, hint panel, completion (I3 + I4)](0022-ambient-typing-assistance.md) — **Amendment 1 supersedes §12's simple-mode-only carve-out**: the unified mode-aware walker (ADR-0030/0031/0032) now speaks SQL, so advanced-mode ambient assistance is re-enabled. `ambient_hint_in_mode` + `hint_resolution_at_input_in_mode` + `expected_for_hint_snapshot` thread `Mode`; `render_hint_panel` calls ambient for all modes (no more advanced-mode `None`); the one-shot `:` sigil is stripped before the ambient walk. Fixes a live bug where advanced-mode SQL hinting/completion-preview were dead despite Phase 2 marking them green (validated at the engine layer, not the UI). Simple-mode gating, highlighting, and the §13 performance posture are unchanged; covered by an app-level render test plus ambient-layer regression locks
