v0.8.3: remove startup info messages from chat history

Remove the add-msg :system calls that printed * Swank <port> * and
* <backend> backend WxH * — purely informational/debug messages
that cluttered the first lines of the chat window.

+The skill loader's sandbox (~core-skills.org~) scans for ~"uiop:run-program"~ as text. This misses indirect calls:
+
+#+begin_src lisp
+(eval (read-from-string "(uiop:run-program \"rm -rf /\")"))
+#+end_src
+
+The jailed package ~:use~s ~:cl~ and ~:passepartout~, so ~eval~, ~find-symbol~, ~intern~, ~funcall~, ~read~ are all available. The post-eval ~symbol-function~ equality check is also bypassable by wrapping.
+
+Fix: add ~eval~, ~funcall~, ~apply~, ~find-symbol~, ~intern~, ~read~, ~read-from-string~ to the text-level ~*skill-restricted-symbols*~ list, and shadow them in the jailed package at load time:
+
+#+begin_src lisp
+(dolist (sym-name '("EVAL" "READ" "READ-FROM-STRING"
+                    "FIND-SYMBOL" "INTERN" "FUNCALL" "APPLY"))
+  (let ((sym (find-symbol sym-name :cl)))
+    (when sym (shadow sym jailed-pkg))))
+#+end_src
+
+This makes the symbols unfindable in the jailed package without an explicit ~cl:eval~ prefix, which the text scan then catches. Text scan + shadowing is the combo that closes the bypass.
+
+~20 lines across ~core-skills.org~. Ships with the eval harness so the harness itself tests the sandbox before use.

 ** v0.10.0: Emacs Development Environment — Secondary Client
 
 cl-tty is the primary TUI (v0.8.0). The Emacs major mode is an optional secondary client for users who prefer Emacs-based workflows. Both clients communicate with the same daemon over the same TCP protocol — they are interchangeable frontends, not competing architectures.

 5. Add ~dispatcher-check-self-termination~: scan shell commands for patterns targeting the Passepartout process (~kill -9 <pid>~, ~rm -rf ~/.cache/passepartout/~, ~sudo apt remove sbcl~). Return ~:reject-self-termination~ with a diagnostic message explaining which command matched and why it would destroy the agent. Human override is possible via HITL — the gate does not prevent the human from issuing the command in a terminal. It prevents the /LLM/ from issuing it accidentally. ~20 lines.
 6. Add ~integrity-verify-core-files~: on heartbeat, hash the eight core files against known-good values stored at daemon startup. On mismatch, inject an integrity alert into the signal queue. ~25 lines, uses existing SHA-256 infrastructure from v0.2.0 Merkle memory.
 
+7. Add CI tangle verification: after checkout, tangle all ~.org~ files, then ~git diff --exit-code~. CI fails if committed ~.lisp~ files don't match canonical ~.org~ source. One CI step in ~.github/workflows/lint.yml~. Also stop ~.gitignore~-ing ~lisp/~ and commit tangled output — lets ~ql:quickload~ work on fresh clone without Emacs.

+8. Add daemon connection thread limits: ~*max-client-connections*~ (default 32), ~*active-client-count*~ with lock, reject connections when at capacity. Add read timeout (~sb-ext:with-timeout~, default 300s) on ~read-framed-message~ to reap silent clients. ~25 lines in ~core-transport.org~.

 *** Verification
 
 Existing FiveAM gate tests continue to pass. New test: signal at type-level 5 targeting a gate at type-level 4 returns ~:reject-type-violation~ without evaluating the gate predicate. New test: signal at type-level 1 passing through a gate at type-level 3 proceeds to predicate evaluation. New test: ~kill -9 <pid>~ returns ~:reject-self-termination~. New test: modified core file is detected by integrity hash check.

+**** Snapshot budget enforcement — extends ~core-memory.lisp~
+
+The current ~snapshot-memory~ deep-copies the entire store. For stores exceeding ~MEMORY_SNAPSHOT_MAX_OBJECTS~ (default 50,000), skip full copies and switch to a journaling mode: record only the objects changed since the last snapshot. Implemented as a conditional branch in ~snapshot-memory~. ~20 lines.

+Add this to the resource self-monitoring heartbeat: before each snapshot, check store size. If over threshold, use journaling path. Keeps the snapshot model viable for the claimed 10M-object use case without requiring 30GB of RAM for 20 snapshots.

 **** External watchdog — extends ~passepartout~ bash entry point
 The bash script spawns a watchdog subprocess that polls the daemon port every ~WATCHDOG_TIMEOUT~ seconds (default 30). If the port stops responding, the watchdog snapshots the last known-good Merkle root, kills the stale process, and restarts the daemon with ~--snapshot <root-hash>~.
