Step 3b: web_search -> EGRESS + the 1.9 egress cards

web_search reclassified EGRESS (spec 2.2, decided 2026-08-12): the destination is
fixed (the configured provider) but the query is model-chosen free text - the same
outbound channel web_fetch's URL is. It ran completely ungated in every mode until
now; it gates like any egress from here on, which also puts it in front of the
Auto-Approve reviewer.

The egress approval cards (spec 1.9):
- web_fetch offers "Always allow <host> this session" -> ALWAYS_DOMAIN. Tool-wide
  "always" is gone from the card AND server-refused (_grant_offered): it would
  cover every future destination, and the live A/B showed exactly that (one click
  on a bbc.com card ran promptless fetches to hosts no card ever named).
- www. stripped at grant minting (allow_domain_for_session) - pure spelling only,
  never eTLD+1. The card button shows the exact spelling the grant mints.
- web_search offers "Always allow searches this session" -> ALWAYS_TOOL (tool-wide
  IS provider-wide for a fixed destination), with the card naming the LIVE
  destination: "Queries go to your configured search provider (currently: <name>)".
  Provider resolved when the card is raised (engine.approval_extras hook), not at
  session start.
- Provider-change invalidation: set_web_search clears the web_search session grant
  in every live engine when the provider actually changes - the grant was consent
  to a named destination.
- Auto-Approve fall-through cards hide every session "always" button: grants don't
  skip the reviewer there (1.5), and a button that lies is worse than none.
- scopeNote tells the truth for egress: "leaves this computer -> <host>" replaces
  "stays on this computer" on fetch/search cards.

Corpora gain web_search cases (benign 22 / dangerous 17 / injection 14), including
query-borne secret exfiltration and a planted search-the-credentials injection.

Tests: test_egress_and_overrides (EGRESS class, gating, www-strip, 1.5 in
Auto-Approve), test_approval_integrity (tool-wide refused for URL-carrying egress,
kept for web_search; provider-change invalidation), ApprovalCard.test.tsx (domain
button + www-strip, provider line, Auto-Approve hides always). Full suites pass;
the 22 pre-existing failures (Slack fake-gateway timeouts, a Windows file-lock
rename) fail identically on the pre-change tree.
