review fixes: every claude create path routes through the workspace-hooks decision

Post-#304 follow-ups. The install-vs-refresh decision (workspaceHooksEnabled,
default ON) moved from a session-routes-local helper into hooks-config.ts as
applyWorkspaceHooks(workspace, install?), and the claude session-create sites
that bypassed it now go through it: cron job fires (cron-service), legacy
scheduled-run iterations (runScheduledLoop), and the plan-orchestrator research
and planner one-shots. A cron or scheduled run firing in a linked case that
never had an interactive session ran hook-blind (no stop for completion
detection, no tab alert on a blocking dialog).

The shared core also carries the two guards every caller needs: a workspace
that no longer exists is skipped (ensureCodemanHooks mkdir -p's, so the boot
recovery sweep used to resurrect a deleted repo as an empty tree holding only
.claude/settings.local.json), and all errors are swallowed since a create must
never fail on hooks. Route handlers keep resolving the setting through their
ConfigPort and pass it in; non-route callers omit it and the core reads
settings.json itself (absent key or unreadable file = ON).

Two adjacent gates tightened in session-routes:
- the docker quick-start hooks branch excluded the five external CLIs but let
  `shell` through, contradicting its own rule that only claude reads .claude
  hooks; it is now gated on mode === 'claude'
- the statusLine exporter call in POST /api/sessions got the same
  !remote && body.workingDir guard the hooks call got in 499d355 (it mkdirs the
  same way, so a remote attach created a junk user@host:session dir locally and
  a cwd-fallback create wrote into $HOME)

plan-routes' one-shot deliberately stays out: its workingDir is process.cwd(),
exactly the target 499d355 forbids writing into. restoreMuxSessions stays out
too: the boot sweep already covers recovered workspaces.

Tests: quick-start existing-case install, docker claude-installs/shell-does-not,
and the core directly (default-ON install, OFF add-nothing, OFF still heals a
stale block, malformed file untouched, vanished workspace skipped); the remote
and cwd-fallback regressions now also send statusLineTelemetry:true to pin the
statusLine guard.
