* fix(agent): clear stale session id when a resumed ACP session is gone
When an agent's stored ACP session no longer exists on the runtime side,
session/resume still succeeds — hermes echoes the requested sessionId
back — so the failure only surfaces when session/prompt returns JSON-RPC
-32603 "Session not found". The backend then reported Status=failed with
the stale SessionID still set, which kept the daemon's resume-failure
fallback (gated on SessionID == "") from ever firing. The failed task
never updates the stored session, so every future mention on the same
(agent, issue) dispatched against the same dead id, forever (#4010).
handleResponse now returns a structured acpRPCError instead of a flat
string (rendered text unchanged), and the hermes/kimi/kiro prompt-error
paths clear the session id when the error is session-not-found class on
a resumed session. The daemon's existing retry then re-executes with a
fresh session and stores the replacement id, healing the mapping.
* fix(agent): clear stale session id when set_model hits a dead resumed session
With a model override, session/set_model runs before session/prompt,
so a resumed session that is gone on the agent side surfaces there
instead of at the prompt — and the error branch returned the stale
SessionID, so the daemon's fresh-session retry (gated on
SessionID == "") never fired. Apply the same clear-the-id fix in the
set_model error branch of all three backends.
Also relax isACPSessionNotFound to accept -32602: kimi-cli raises
RequestError.invalid_params({"session_id": "Session not found"}) for
every unknown-session path (src/kimi_cli/acp/server.py), so pinning
-32603 made the fix dead code for kimi. The wording gate keeps
unrelated invalid_params errors (e.g. "model not available") on the
preserve-the-id path.
Regression tests for all three backends: resumed session + model
override + set_model failing with each runtime's observed
session-not-found shape must yield status=failed with an empty
SessionID.
* MUL-2764 feat(agent): wire mcp_config through ACP runtimes (Hermes / Kimi / Kiro)
The MCP config Tab (#3419) already lets admins save mcp_config on an
agent, and the daemon plumbs it through to `agent.ExecOptions.McpConfig`
for every runtime. Claude and Codex consume it; the three ACP runtimes
(Hermes / Kimi / Kiro) ignored the field and hardcoded an empty
`mcpServers: []` in their `session/new` requests.
Add `buildACPMcpServers` to translate the Claude-style `{"mcpServers":
{"<name>": {...}}}` object-of-objects into the array shape ACP requires
(`[{name, command, args, env: [{name,value}, ...]}, ...]` for stdio;
`[{type, name, url, headers: [...]}, ...]` for http/sse), then pass the
translated array on `session/new` (all three) and `session/load` (kiro
resume). Malformed JSON fails the launch closed — same contract Codex's
`renderCodexMcpServersBlock` uses — so users see a real error instead of
silently running with no MCP servers. Individual unclassifiable entries
(no command, no url) are skipped with a warning so one bad row can't
take MCP down for the rest of the agent.

* MUL-2764 fix(agent): wire mcp_config through ACP resume + gate http/sse on capability
Addresses the two blockers Elon raised on #3439:
1. session/resume now carries mcpServers for Hermes and Kimi (Kiro's
session/load already did). Per the ACP Session Setup spec the resume
path re-attaches MCP servers, and without this a resumed task lost
access to MCP tools that a fresh task on the same agent would have
had. Pinned with new TestHermesResumeIncludesMcpServers and
TestKimiResumeIncludesMcpServers integration tests that inspect the
recorded wire request.
2. Added extractACPMcpCapabilities + filterACPMcpServersByCapability so
http/sse MCP entries get dropped (with a daemon-log warning naming
the entry) when the runtime's initialize response doesn't advertise
mcpCapabilities.http / .sse. Sending those entries to a stdio-only
runtime is a spec violation and reliably tanks session/new; now they
get filtered and the rest of the session still starts. Stdio entries
pass through unconditionally. Both backends wire the filter in right
after initialize so session/new and session/resume see the same
filtered list.
Also added TestKiroLoadIncludesMcpServersFromConfig — Elon flagged that
no test pinned "non-empty mcp_config actually reaches the wire" for
Kimi/Kiro, so the wire assertions go in for all three runtimes.

Ignore Kiro ACP session/load history replay before the active prompt starts; keep task messages, usage, and tool state scoped to the current Kiro turn. Verified with go test ./pkg/agent -run TestKiro, go test ./pkg/agent, and git diff --check origin/main...HEAD.
