Merge branch 'dev' into feature/ssh-support

Brings dev's retry-with-backoff (the transient `provider-retry` AgentEvent the
web frontend consumes) + the LSP-dead-server per-edit-hang fix into the SSH
feature branch, alongside the SSH waves 0-5c.

All code files auto-merged cleanly (run-turn.ts, orchestrator.ts, runtime.ts,
wire/index.ts, tool-edit-file/extension.ts, run-turn.test.ts — both computerId
threading and retry-with-backoff coexist). Only tasks.md conflicted (status
section — orchestrator-resolved; both feature sections kept).

Verified post-merge: tsc -b EXIT 0, biome clean (391 files), 1730 vitest pass
+6 sshd-integration skipped (was 1690; +40 from dev's retry/LSP tests).
Wire dist rebuilt so the FE can re-sync the pinned @dispatch/wire dep and pick
up BOTH provider-retry AND the SSH Computer/defaultComputerId types.
No merge or push (into dev or otherwise).
