* fix(ui): echo slash command input as user message in chat (#840)

Slash commands like /skills, /help, /status previously showed only the
assistant response with no user message above it — the conversation
appeared to start from nowhere.

Fix: executeCommand() now returns {noEcho:bool} instead of true/false
(returns null when no command matched). send() in messages.js pushes a
user message bubble before returning when noEcho is false.

Commands with noEcho:true are action-only and don't get echoed:
/clear, /new, /stop, /retry, /undo, /voice, /model, /workspace,
/theme, /usage, /reasoning.

Commands without noEcho (get echoed):
/help, /skills, /status, /title, /compress, /compact, /personality.

16 new tests in test_issue840_slash_echo.py.

* fix(ui): push user message BEFORE running slash handler (ordering bug)

The PR as originally written pushed the user message AFTER the slash
command handler ran.  That works correctly for async handlers (the
assistant response lands later, after the user push) but breaks for
sync handlers like cmdHelp which push their assistant response
synchronously:

  S.messages = [assistant response, user "/help"]   ← reverse order

The chat would render the help content ABOVE the user's own "/help"
input — not what the issue asked for.

Fix: look up the command inline, push the user message first (for
echo-worthy commands), then run the handler.  If the handler opts out
(returns false — e.g. /reasoning <level>), pop the user message back
off so the normal send path can add it cleanly when forwarding to the
agent.

Renamed the flow so it's clear we're not calling executeCommand twice
(my first attempt did that by accident).  executeCommand() stays as a
public API returning null or {noEcho:bool} — just isn't the only path
send() uses now.

Added 2 regression tests:

- test_send_pushes_user_message_before_running_handler: asserts
  the user push appears before the handler invocation in source order.
- test_send_rolls_back_user_push_on_handler_optout: asserts the
  S.messages.pop() for the opt-out case.

Also tightened the existing `test_send_checks_noecho_flag` and
`test_send_pushes_user_message_for_echo_commands` tests to look at
the new `_cmd.noEcho` pattern inline (vs the original
`cmdResult.noEcho`).  Removed `test_send_uses_null_check_not_truthy`
(obsoleted — the control flow no longer stores the executeCommand
return in a variable).

Full suite: 1767 passed, 0 failures.

* fix(ui): compress/compact noEcho + title/personality confirmation messages

Applied Opus mentor review fixes:
- compress and compact: add noEcho:true (S.messages reset internally causes
  user bubble to flicker/disappear without noEcho)
- /title <name>: push assistant confirmation message after rename succeeds
- /personality <name>: push assistant confirmation message after set succeeds
- 4 new regression tests covering the above invariants
