yushen 077e40c638 MUL-3284 PR2 (daemon): pull profiles, PATH-resolve, register, exec command
Daemon-side half of custom runtime profiles, against the server contract on
this branch.

- client.go: GetRuntimeProfiles(workspaceID) -> GET
  /api/daemon/workspaces/{id}/runtime-profiles (mirrors GetWorkspaceRepos);
  RuntimeProfile / RuntimeProfilesResponse types.
- types.go: Runtime gains profile_id (parsed from the register response so
  runtimeIndex carries it).
- daemon.go:
  * appendProfileRuntimes — called inside registerRuntimesForWorkspace before
    the empty-runtimes guard. Best-effort fetch (older server 404s are logged
    and swallowed; never fails registration). Per enabled profile: resolve
    command_name via PATH (exec.LookPath, behind a `lookPath` test hook),
    skip+log when absent, best-effort version probe, record the resolved
    absolute path keyed by profile_id, and append a registration entry
    {name, type=protocol_family, version, status:online, profile_id}. A
    custom-only host (no built-in agents) still registers.
  * profileCommandPaths map (guarded by d.mu) + recordProfileCommandPath /
    customCommandPathForRuntime helpers.
  * runTask: looks up the claimed task's RuntimeID -> profile command path and
    overrides the executable path, synthesizing an AgentEntry so a custom
    runtime runs even when the host has no built-in agent of the same
    provider. provider (=protocol_family) is unchanged so agent.New still
    selects the right backend.
- Tests: GetRuntimeProfiles request shape; profile runtime appended + path
  recorded (custom-only host); profile skipped when command not on PATH;
  profiles-fetch-404 is best-effort; customCommandPathForRuntime bookkeeping.
- agent: lockstep test pinning SupportedTypes to agent.New and the migration
  120 protocol_family CHECK.

Iron rule honored: profile carries no generic per-agent args. fixed_args are
parsed and carried but intentionally NOT wired into the launch command yet
(optional/best-effort; explicit TODO(MUL-3284) in appendProfileRuntimes).

Verified: go build ./... clean; go vet ./internal/daemon/... clean;
go test ./internal/daemon/... pass (existing + 5 new); full
go test ./internal/handler/ suite passes against a migrated Postgres 17;
agent lockstep test passes.
