* feat: enable workers to message orchestrator via AO_ORCHESTRATOR_SESSION_ID
Worker sessions can already be messaged by the orchestrator via `ao send`,
but the reverse direction was undiscoverable: workers had no way to learn
their orchestrator's session ID. The transport already exists (`ao send`
routes to any session in the project, and the orchestrator's ID is
deterministic at `${sessionPrefix}-orchestrator`) — only the discoverability
piece was missing.
Changes:
- Add `orchestratorSessionId?: SessionId` to `AgentLaunchConfig`.
- Populate it in spawnWorker and the worker restore path; deliberately
omit it for spawnOrchestrator (an orchestrator is not its own parent).
- Each agent plugin (claude-code, codex, opencode, aider, cursor, kimicode)
now injects `AO_ORCHESTRATOR_SESSION_ID` into the agent env when the
field is present.
- Worker prompt preamble teaches the new channel with two restraints:
(1) only ping when genuinely blocked, (2) always prefix with
`[from $AO_SESSION_ID]` because the orchestrator receives raw input
with no `from:` metadata.
No new CLI verb, no new file format, no new transport — just env wiring
plus prompt copy.
Closes#1786

* fix: only set AO_ORCHESTRATOR_SESSION_ID when orchestrator metadata exists
Greptile review on #1787: spawn() unconditionally injected the env var
for every worker, including ad-hoc `ao spawn` workers in projects that
never had an orchestrator running. The AgentLaunchConfig JSDoc claimed
the field was unset for ad-hoc sessions, but the implementation didn't
honor it — so a worker following the prompt's `ao send
$AO_ORCHESTRATOR_SESSION_ID …` instruction would get an opaque
"session does not exist" error.
Both spawn() and restore() now check `readMetadataRaw(sessionsDir,
"<prefix>-orchestrator")` and only propagate the field when the
orchestrator's metadata is actually on disk. Existence-on-disk is the
right signal: if metadata was ever written for the canonical
orchestrator ID, the orchestrator workflow is in play for this project.
Tests updated:
- spawn: split into two cases — "passes when orchestrator exists" (now
spawns the orchestrator first) and "omits for ad-hoc workers".
- restore: added a third case for ad-hoc worker restore (no orchestrator
metadata) alongside the existing worker-with-orchestrator and
orchestrator-restore cases.

* fix: document orchestrator-send command for POSIX, PowerShell, and cmd.exe
Greptile review on #1787: the prompt's `ao send $AO_ORCHESTRATOR_SESSION_ID
"[from $AO_SESSION_ID] …"` example is bash-only. On Windows PowerShell
(the default shell), bare `$AO_ORCHESTRATOR_SESSION_ID` resolves to
$null, so the command silently sends to an empty session ID instead of
the orchestrator. CROSS_PLATFORM.md flags exactly this footgun.
Both prompt variants now show the correct form for the three shells AO
supports as a first-class platform: POSIX bash/zsh, PowerShell
(`$env:NAME`), and cmd.exe (`%NAME%`). The agent picks the form for its
shell. Quotes added around the POSIX expansion as a defensive measure
in case the env var ever expands to whitespace.
prompt-builder tests now assert all three syntaxes appear in both the
full and no-repo prompts.

* refactor: literal-render orchestrator ID in prompt; auto-prefix [from <id>] in ao send
Two simplifications collapsed into the same feature now that the
worker→orchestrator dialogue lives in the prompt + send.ts only:
1. **Drop AO_ORCHESTRATOR_SESSION_ID env var entirely.** The orchestrator
session ID is deterministic (`${sessionPrefix}-orchestrator`) and known
at prompt-build time, so prompt-builder just renders it literally:
ao send my-orchestrator "<your message>"
No env var, no AgentLaunchConfig field, no per-plugin wiring, no
PowerShell/cmd.exe/POSIX shell-syntax variants. The orchestrator
existence check moves into session-manager's buildPrompt call site —
one place instead of duplicated across env injection + prompt mention.
2. **Auto-prefix `[from $AO_SESSION_ID]` in `ao send` itself.** The prompt
no longer teaches the agent to self-identify because that's
infrastructure's job. send.ts wraps the message when AO_SESSION_ID is
set, which covers all session→session traffic (worker→orchestrator,
orchestrator→worker, worker→worker). Humans running ao send from
their own terminal stay unprefixed.
Net: 21 files changed, +174 / −249. Zero plugin code touched. No
cross-platform shell footgun.
Files:
- types.ts: drop orchestratorSessionId field
- session-manager.ts: drop spawn/restore field injection; pass
orchestratorSessionId into buildPrompt instead, gated on metadata
existence on disk
- 6 agent plugins: drop AO_ORCHESTRATOR_SESSION_ID env injection + tests
- prompt-builder.ts: add orchestratorSessionId to PromptBuildConfig;
conditionally emit "Talking to the Orchestrator" section with literal
ID; remove the section from the static base prompts
- send.ts: auto-prefix when AO_SESSION_ID is set
- send.test.ts: 3 new tests for prefix-set / prefix-unset / SessionManager
delivery; existing tests preserved by clearing AO_SESSION_ID in beforeEach
- changeset: scope drops to ao-core + ao-cli only
