* MUL-2764: feat(agents): add MCP config tab to agent detail page
Backend already stores `mcp_config` and the daemon forwards it to the
runtime CLI via `--mcp-config`; this only adds the UI entry point.
The new tab presents a JSON editor that pretty-prints the existing
config, validates the buffer on every keystroke, and saves through the
existing `PUT /api/agents/{id}` path. Clearing the editor sends
`mcp_config: null`, which the handler reads as "wipe the column" and
the daemon falls back to the CLI's own default.
When the caller can't see secrets (agent actor, or a non-owner
non-admin member), the server already returns `mcp_config: null` with
`mcp_config_redacted: true`; the tab renders a read-only "configured
but hidden" state in that case so a non-privileged member cannot
silently overwrite an admin-owned config by saving an empty editor.

* fix(agents): MCP tab — preserve in-flight edits + warn non-Claude runtimes
- Fix stale-editor sync: compare the local draft against the *previous*
original via a ref, so a background agent refetch updates an untouched
editor instead of being silently ignored. Without this, a draft equal to
the OLD original was treated as user-edited after the prop changed, and
the next Save would write the old config back over a concurrent admin
edit.
- Surface a notice inside the tab when the agent's runtime provider is not
Claude — today's daemon only forwards mcp_config via Claude's
--mcp-config, so saving on e.g. a Codex agent was silent but ineffective.
- Tests for both: rerender resyncs an untouched editor, rerender preserves
an in-flight edit, warning renders on non-Claude / hides on Claude.

* MUL-2764: feat(agents): codex MCP support + hide MCP tab on unsupported runtimes
- Backend: codex.go now translates agent.mcp_config (Claude-style
`{"mcpServers": {...}}`) into `-c mcp_servers.<name>=<inline-toml>`
flags for `codex app-server`, so MCP servers configured in the UI
reach Codex's per-task config layer. Bad mcp_config JSON downgrades
to a warn-and-skip so it can't break the agent launch.
- Frontend: AgentOverviewPane hides the MCP tab when the agent's
runtime provider doesn't read mcp_config — only `claude` and `codex`
are supported today, every other provider sees no MCP tab. The
previous in-tab warning is removed (no longer reachable).
- New shared helper `providerSupportsMcpConfig` lives in
`@multica/core/agents` so views and any future caller share one list
of MCP-aware providers.
- Tests: new go-side coverage for stdio + url + multi-server inputs,
TOML string escaping, malformed-input fallback, and arg ordering vs
custom_args; new views-side coverage for which providers surface the
MCP tab. En + zh-Hans copy and parity test refreshed.

* MUL-2764: fix(agents): keep codex mcp_config secrets out of argv/logs
Move the agent's mcp_config from a `-c mcp_servers.<id>=<inline-toml>`
argv flag into a daemon-managed `[mcp_servers.*]` block inside the
per-task `$CODEX_HOME/config.toml`. mcp_servers.<id>.env is a documented
Codex config field and the UI already treats mcp_config as redacted for
non-admins; argv would have leaked those values into `ps aux` and the
`agent command` log line. The file is forced to 0600 to keep secrets in
the daemon owner's lane regardless of the seed file's mode.
Also drop user-supplied `-c/--config mcp_servers.*` entries from
custom_args. Codex `-c` is last-wins (verified against codex-cli 0.132.0),
so without filtering, a custom_args entry could silently shadow whatever
the MCP Tab saved.
Strip inherited `[mcp_servers.*]` tables from the per-task config.toml
when the agent has its own mcp_config, mirroring Claude's
`--strict-mcp-config`: avoids TOML "table already exists" errors on
name collisions and matches admin expectations that the MCP Tab is the
authoritative source for that task.

* MUL-2764: fix(agents): codex mcp_config three-state semantics + custom_args compat
Address the third review pass:
1. Distinguish nil vs present-but-empty mcp_config. `{}` and
`{"mcpServers":{}}` now count as "admin saved an explicit (empty)
managed set" — strip inherited user `[mcp_servers.*]` and pin an
empty managed marker block. Only SQL NULL / JSON `null` map to
"absent" and fall back to the user's global `~/.codex/config.toml`.
This aligns Codex with the API's three-state contract (omit / null
/ object) and with Claude's `--strict-mcp-config` semantics.
2. Fail closed on `ensureCodexMcpConfig` errors and on managed
mcp_config without CODEX_HOME. Previous warn-and-launch would
silently inherit the user's global MCP servers and look identical
to a successful apply — exactly the surprise the MCP Tab is meant
to remove.
3. Only filter `-c mcp_servers.*` from `custom_args`/`extra_args`
when the agent has a managed mcp_config. Pre-MUL-2764 agents that
configured MCP via custom_args keep working; once an admin opts
in via the MCP Tab the daemon owns the `mcp_servers` namespace
and overrides are dropped (last-wins safety).
4. Update mcp_config locale intro to mention $CODEX_HOME/config.toml
instead of the now-removed `-c mcp_servers.*` argv path.
Tests:
- Split `TestEnsureCodexMcpConfigEmptyInputsAreNoop` into
`TestEnsureCodexMcpConfigAbsentLeavesUserTablesAlone` (nil/null)
and `TestEnsureCodexMcpConfigEmptyManagedSetStripsUserMcp` (`{}`,
`{"mcpServers":{}}`).
- Add `TestEnsureCodexMcpConfigEmptyManagedSetIdempotent` to pin
byte-identical reruns on the empty managed marker block.
- Add `TestHasManagedCodexMcpConfig` covering the eight relevant
inputs.
- Add `TestBuildCodexArgsPreservesCustomMcpOverridesWhenUnmanaged`
and `TestBuildCodexArgsDropsCustomMcpOverridesWhenManaged` to
pin the new gating.
- Add `TestCodexExecuteFailsClosedWhenMcpConfigInvalid` and
`TestCodexExecuteFailsClosedWhenManagedMcpButNoCodexHome` for the
Execute paths.
