feat(agent): adopt AI SDK v7 — crash safety, context pruning, HITL approvals (#3362)

* docs(adr): propose agent AI SDK v7 adoption plan

* fix(ai): bind analyzeResume through aiService in service test

The test destructured analyzeResume as a named export that does not exist; main was red.

* test(agent): keep pure ai helpers real via spread-actual mock factory

* feat(agent): add run guards, patch version guard, run wall-clock timeout

* feat(agent): validate UI messages at the send boundary

* feat(agent): crash-safe draft-row persistence and server-side cancellation

* feat(agent): reap stale run claims at boot, on send, and on thread open

* feat(agent): fresh-document patch output and tiered context pruning

* feat(ai): shared agent tool contracts and message metadata schema

* feat(agent): add per-thread review-patches setting with update endpoint

* feat(agent): gate resume patches behind hmac-signed tool approval

* feat(agent): merge question answers and approval decisions before run claim

* feat(agent): approval ui with composed auto-send and fixture-driven tests

* feat(agent): usage metadata, tool activity cards, smoother streaming

* feat(agent): tool-call repair, input examples, structured step logging

* chore(i18n): translate new agent workspace strings across all locales

* fix(agent): gate stale-run draft cancellation on winning the claim clear

Snapshot streaming drafts before the conditional clear and skip the flip entirely when another reaper or a replacement run already cleared the claim. Also address review nits in eleven locale catalogs.

* fix(agent): flip reaped drafts only when their snapshotted state is unchanged

* fix(agent): address review findings across run lifecycle, context budget, and approval flow

- bind patches to the revision the model read via signed baseUpdatedAt
- claim the run before consuming a continuation; recorded-but-unexecuted approvals retry as pending continuations
- keep run ownership on stop() until cancellation persists; preserve the claim for the reaper when final persistence fails
- estimate tokens without serializing binary attachments (tokenx) and enforce the budget by dropping oldest whole turns
- mark crash-recovered patch results as snapshot boundaries; strip /data prefixes at execution time
- retry failed continuations without regenerate; mount a single AgentChat; disable response controls on read-only threads; freeze review toggle during runs (client+server)
- accumulate usage across continuations and match the SDK's nested usage shape; label-form token strings; reorderable source label; accessible note field; state-neutral web-search label

* chore(i18n): translate revised agent strings across all locales

* fix(agent): harden baseUpdatedAt validation and address review follow-ups

- bundle tokenx in the server runtime dependencies (e2e boot failure)
- strict ISO schema for baseUpdatedAt plus loud executor rejection of unparseable values
- it-IT source label consistency (Fonte)
- prove penultimate-turn retention in the context pruning test

* chore(deps): exempt tokenx from knip for the externalized server bundle
