release(v4.6.150): commit the module work that has been live but uncommitted

Operator commit-approve, 2026-11-06. These changes have been served since
2026-11-02/03 while git HEAD still stamped v4.6.146, so the mirror published a
tree four builds behind the running instance and the release tag named the
wrong build.

module-orchestrator.js — orchestrate-parallel reported success it could not
prove. Results are now recorded by sub-task id through a resultSink handed to
delegateTask (harvest matched by currentTask/lastTask strings, which a later
delegation on the same agent overwrote, losing finished work as "agent not
found"); the tally counts summaries with status ok instead of
Promise.allSettled resolutions (a spawn refusal fulfils with undefined and used
to print green); and a busy agent is no longer reused at pool cap, where two
siblings erased each other's lease. Guard:
modules/test/test-orchestrator-parallel-harvest.js (16 cases, reproduces the
one-agent three-sub-task cap case that printed 3/3 succeeded).

module-billing.js — the balance said "not signed in — newOS4 sends no session
token", which was already false: the browser sends the HttpOnly cookie and
parse_bearer_token() falls back to it. `cost` is on by default (the flag was
opt-in and nobody knew the command existed; `cost off` opts out) and the
command now prints today's platform spend from GET /api/billing/usage?days=1
alongside the session estimate.

modules/ext/webdav.js — the inline WebView detector missed "Version/4.0"
Android WebViews, including the operator's own phone, so the login offered a
Telegram widget that cannot complete there. It now delegates to
modules/wx11-tg-webview.js when the page loaded it and keeps a matching
fallback (wv token, Version/4.0-Android, Telegram, FBAN/Instagram/Line).

modules/ext/media.js — text analysis model renamed deepseek-v4-flash ->
deepseek-v4.1-flash in both the field and the printed label.

main.html + module-loader.js — v4.6.146 -> v4.6.150 in LATEST_VER and the three
asset queries; core-bundle.js rebuilt (rebuild-bundles.py reports it already
in sync, 1,250,569 bytes).

Verified: node --check on all six scripts and the new test; the 16-case
orchestrator guard passes against the deployed bundle (ORCH_SRC=...); bundle
rebuild is a no-op; core-bundle.js?v=v4.6.150 answers 200.
