Garry Tan c7583f7f02 fix: pre-landing review findings (4 auto-fixes)

Addresses 4 findings from the Claude adversarial subagent on the
v1.6.0.0 security wave diff.  No user-visible behavior change; all
are defense-in-depth hardening of newly-introduced code.

1. GET /connect rate-limited (was POST-only) [HIGH conf 8/10]
   Attacker discovering the ngrok URL could probe unlimited GETs for
   daemon enumeration.  Now shares the global /connect counter.

2. ngrok listener leak on tunnel startup failure [MEDIUM conf 8/10]
   If ngrok.forward() resolved but tunnelListener.url() or the
   state-file write threw, the Bun listener was torn down but the
   ngrok session was leaked.  Fixed in BOTH /tunnel/start and
   BROWSE_TUNNEL=1 startup paths.

3. GSTACK_SKILL_ROOT path-traversal gate [MEDIUM conf 8/10]
   Symmetric with E3's GSTACK_SLUG regex gate — reject values
   containing '..' before interpolating into the welcome-page path.

4. SSE session registry pruning [LOW conf 7/10]
   pruneExpired() only checked 10 entries per mint call.  Now runs
   on every validate too, checks 20 entries, with a hard 10k cap as
   backstop.  Prevents registry growth under sustained extension
   reconnect pressure.

Tests remain green (56/56 in sse-session-cookie + dual-listener +
pair-agent-e2e suites).
