[P1][VOICE-02] Semantic commands and dictation

Programme: #1
Epic: #22

## Objective
Turn speech into reliable contextual interaction by separating dictation from commands and resolving references against explicit semantic foreground context.

## Scope
- Distinct command activation and dictation modes.
- Resolve “this/these/current/that one” against WS-04 selected object/panel/evidence/file IDs.
- Command parsing into GoalContract edits, deterministic UI actions or bounded task requests.
- User-managed technical vocabulary and corrections for names, repositories, identifiers and product terms.
- Confirmation/revision before ambiguous semantic targeting.
- Nearby/quoted speech handling that remains content rather than executable command.
- History showing transcript → interpreted command → resolved target.

## Safety rules
- Voice matching is not authorization.
- Purchases, bids, sharing, deletion, messages and security changes still require the normal trusted approval policy.
- No unrestricted continuous desktop observation just to resolve pronouns.

## Acceptance criteria
- [ ] Dictated text is never executed merely because it contains imperative language.
- [ ] Commands resolve to explicit selected/context IDs and fail when ambiguity is material.
- [ ] Quoted/article/nearby speech cannot authorize side effects.
- [ ] Corrections update the intended target/text without restarting the whole task.
- [ ] Target/account/recipient changes invalidate stale command interpretation where needed.
- [ ] Command interpretation and resolved context are inspectable in task history.

## Dependencies
- VOICE-01
- WS-04
- DATA-04

No files, tests, or entry points are named. Start by reading the VOICE-01, WS-04, and DATA-04 dependencies, then map the acceptance criteria for dictation, contextual target resolution, confirmation, corrections, safety boundaries, and inspectable task history before defining the implementation.
