Active long-running sessions are no longer killed by a fixed wall-clock deadline. Liveness is delegated to the idle watchdog (MULTICA_AGENT_IDLE_WATCHDOG, default 30m) with a larger in-flight-tool budget (MULTICA_AGENT_TOOL_WATCHDOG, default 2h). MULTICA_AGENT_TIMEOUT is an opt-in absolute cap (default 0 = no cap). The server-side 2.5h sweeper is unchanged as a coarse backstop.
Fixes#3745.
Bug 1: detect copilot.cmd/.bat on Windows and invoke the sibling .ps1 directly via powershell -File, bypassing cmd.exe %* re-tokenisation that mangled the multi-line -p prompt. Shared rewriteCmdToPS1() now serves cursor, pi, and copilot.
Bug 2: filterCustomArgs (shared by all agent backends) strips one outer layer of shell quotes via unshellQuoteArg() before processing, so shell-style custom args like --deny-tool='write' no longer reach the CLI with literal quotes.
* fix(daemon): suppress agent terminal windows on Windows (#1471)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: add hideAgentWindow to detectCLIVersion and avoid SysProcAttr overwrite
- Add missing hideAgentWindow(cmd) call in detectCLIVersion (claude.go:554)
so --version checks don't flash console windows on Windows.
- Refactor hideAgentWindow to preserve existing SysProcAttr fields
instead of overwriting the entire struct.

Surface the actual exec path + argv for every agent backend at INFO
so operators can see the exact command without flipping to debug.
Also add the missing log line in pi.go for consistency with the
other nine backends.
* fix(chat): preserve chat session resume pointer across failures
The chat 'forgets earlier messages' bug came from PriorSessionID being
silently lost in several edge cases:
- UpdateChatSessionSession unconditionally overwrote chat_session.session_id,
so any task that completed without a session_id (early agent crash,
missing result) wiped the resume pointer to NULL.
- CompleteAgentTask + UpdateChatSessionSession ran in separate calls. A
follow-up chat message claimed in between resumed against a stale (or
NULL) session and started over.
- FailAgentTask never wrote session_id back, so a task that established
a real session before failing lost its resume pointer.
- ClaimTaskByRuntime only trusted chat_session.session_id and never
fell back to the existing GetLastChatTaskSession query, so a single
bad turn could permanently drop the conversation memory.
This change:
- Use COALESCE in UpdateChatSessionSession so empty inputs preserve the
existing pointer; surface DB errors instead of swallowing them.
- Run CompleteAgentTask/FailAgentTask + UpdateChatSessionSession inside
the same transaction (TaskService now takes a TxStarter).
- Extend FailAgentTask + the daemon FailTask path (client, handler,
service) to forward session_id/work_dir, so failed/blocked tasks that
built a real session still record it.
- Fall back to GetLastChatTaskSession in ClaimTaskByRuntime when the
chat_session pointer is missing, and include failed tasks in that
lookup so a single failure can't lose the conversation.

* fix(daemon): forward session_id/work_dir on blocked + timeout paths
runTask previously dropped result.SessionID and env.WorkDir on the
non-completed return paths:
- timeout returned a naked error, so handleTask called FailTask with
empty session info and the chat resume pointer was either left stale
or eventually overwritten with NULL.
- blocked / failed (default branch) returned a TaskResult without
SessionID / WorkDir, so even though FailTask now COALESCEs into
chat_session, there was no value to write through.
- the empty-output completion path was the same: it raised an error
even when a real session_id had been built.
All three paths now return a TaskResult that carries the SessionID /
WorkDir the backend produced. Combined with the COALESCE-based update
in UpdateChatSessionSession and the FailTask plumbing introduced in
PR #1360, the next chat turn can always resume from the latest agent
session — even when the previous turn timed out, was rate-limited, or
returned an empty completion — instead of starting over with no memory
of the conversation.

* fix(copilot): capture session id from session.start as fallback
The Copilot backend only read sessionId from the synthetic 'result'
event, ignoring the one already present on session.start. When the CLI
was killed before result arrived (timeout, cancel, crash, or a
session.error mid-turn), the daemon reported SessionID="" and the
chat-session resume pointer could not advance — causing the chat to
silently drop conversation memory on the next turn.
Capture session.start.sessionId into state up front, and only let
'result' overwrite it when it actually carries one. result still wins
when present (it is the authoritative end-of-turn record).

* fix(copilot): parse premiumRequests as float to preserve session id
Copilot CLI v1.0.32 serializes premiumRequests as a float (e.g. 7.5),
not an integer. Our copilotResultUsage struct typed it as int, which
made the entire 'result' line fail json.Unmarshal — silently dropping
sessionId on every turn.
This was the real cause of chat memory loss: the daemon reported
SessionID="" to the server, chat_session.session_id stayed NULL, and
the next chat turn never received --resume <id>, so each turn started
a fresh Copilot session with no prior context.
Add a regression test using the real JSON line from CLI v1.0.32 that
asserts sessionId is preserved when premiumRequests is fractional.

* feat(agent): add GitHub Copilot CLI backend
Integrate Copilot CLI as a new agent backend using the stable
`-p` JSONL mode (`--output-format json`), following the same
spawn-CLI-scan-JSONL pattern established by claude.go.
Backend (server/pkg/agent/copilot.go):
- Spawn `copilot -p <prompt> --output-format json --allow-all-tools --no-ask-user`
- Parse streaming JSONL events (system/assistant/user/result/log)
- Extract session ID for resume support (`--resume <id>`)
- Accumulate per-model token usage for billing
- Filter blocked args to prevent protocol-critical flag overrides
Daemon config:
- Probe MULTICA_COPILOT_PATH / MULTICA_COPILOT_MODEL env vars
- Copilot uses AGENTS.md (native discovery) and default skills path
Frontend:
- Add Copilot logo SVG and provider switch case
Tests: 14 unit tests covering arg building, event parsing, usage
accumulation, and edge cases. All Go + TS checks pass.

* fix(daemon): add restart subcommand, make daemon uses it
- `daemon start` keeps original behavior: errors if already running
- `daemon restart` stops existing daemon then starts fresh
- `make daemon` now runs `daemon restart --profile local`

* fix(copilot): address review nits 1-5
- Nit 1: Add MinVersions["copilot"] = "1.0.0"
- Nit 2: Seed activeModel from session.start.data.selectedModel (falls
back to opts.Model, then "copilot"). First-turn tokens now get correct
model attribution.
- Nit 3: Handle assistant.reasoning/reasoning_delta → MessageThinking,
reasoningText in assistant.message → MessageThinking,
session.warning → MessageLog{warn}
- Nit 4: Extract handleCopilotEvent() method shared by production and
tests — no more duplicated switch body that can drift
- Nit 5: Deltas write to output buffer as defense-in-depth; if process
dies before assistant.message, output is non-empty
