Merge master into refactor/envoverrides-tmux-export

Resolved conflict in src/web/public/session-ui.js by keeping this
PR's buildEnvOverrides() helper — it already covers both
CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS (this PR) and
CLAUDE_CODE_EFFORT_LEVEL (added in #73), so the master-side inline
block is fully replaced.

Also fixed test/session-manager.test.ts MockSession to add a
getEnvOverridesForPersist() stub — without it,
SessionManager.updateSessionState's new call breaks 19 tests with
"TypeError: session.getEnvOverridesForPersist is not a function".

Verified: typecheck, lint, format:check, build, and
test/{session-manager,session-state,tmux-manager,tmux-restart-recovery}.test.ts
all pass.
