bump model registry for deepseek v4, kimi k2.6, claude opus 4.7 (#554)

* bump model registry for deepseek v4, kimi k2.6, claude opus 4.7

deepseek released v4 (pro/flash) on 2026-04-24 as a generational replacement
for v3-era reasoner/chat. deepseek will fully retire deepseek-chat and
deepseek-reasoner on 2026-07-24 — both already route server-side to v4-flash.
introduce deepseek-pro (preferred) and deepseek-flash slugs and mark the
legacy aliases deprecated via fallback so existing users transparently
upgrade. mirror on the openrouter side.

also bump moonshotai/kimi to k2.6 (from k2.5, 2026-04-21 release) and bump
the anthropic claude-opus openrouter resolves to 4.7 (we'd already moved the
native side to claude-opus-4-7 but openrouter resolves still pointed at 4.6).
update OSS_PROXY_MODEL fallback and stale doc reference accordingly.

snapshot regenerated; all 111 catalog tests + 66 unit tests pass.

* walk fallback chain when resolving the OSS proxy model

the OSS proxy path in run-context/route.ts read alias.openRouterResolve
directly, bypassing the fallback chain. so an OSS repo configured with
deepseek/deepseek-reasoner kept proxying to openrouter/deepseek/deepseek-v3.2
instead of resolving through the new fallback to openrouter/deepseek-v4-pro.
that worked today (v3.2 routes server-side to V4-Flash) but breaks when
deepseek and openrouter retire v3.2 alongside the 2026-07-24 deprecation.

extract the chain walk into a private resolveTerminalAlias helper and add
resolveOpenRouterModel that mirrors resolveCliModel but returns
openRouterResolve. fallback semantics now apply uniformly across both
runtime resolution paths.

* hide deprecated aliases from model selector dropdowns

aliases with a fallback (currently deepseek-reasoner / deepseek-chat /
openrouter/deepseek-chat) should not be selectable from the model dropdown
or the interactive cli model picker — they're a transition path, not a
choice. but if a repo already has a deprecated slug stored in the db, the
selector trigger still resolves it against the full alias registry so the
display name renders correctly until the user opens the menu and picks a
new model.

verified manually: deepseek submenu shows pro+flash only, openrouter submenu
shows pro+flash but no chat, and a deprecated stored value still renders
its full display name in the trigger.

* ci: run models-live on PRs that touch resolution files

Previously the per-alias smoke matrix only fired on push-to-main, so
resolution-affecting PRs (this one included) shipped without ever
exercising the agent harness against the real provider for each alias.

Loosen the gate on the `aliases` step in the `changes` job to fire
whenever the `models` paths-filter matches (action/models.ts,
action/package.json, action/agents/**) — same set that already drives
the comment about "resolution-affecting files". `models-live` itself
is unchanged: it still keys on a non-empty matrix.

`models-catalog` stays gated to main-push intentionally — its existing
comment justifies that (transient upstream catalog drift shouldn't
block PRs).

* relabel codex aliases as GPT, bump to 5.5 family, add gpt-pro

OpenAI retired the "-codex" model suffix on 2026-07-23 (gpt-5.3-codex,
gpt-5.1-codex-mini, gpt-5.2-codex et al all shut down) and unified the
codex+gpt lines into a single family at gpt-5.4. Per OpenAI's own
deprecation table, every "-codex" substitute is plain gpt-5.x — no
future Codex-suffixed frontier models are coming.

Keep the existing slugs for DB stability (no migration needed) but roll
displayName + resolve forward across openai, opencode, and openrouter:

- openai/gpt-codex       → "GPT"      → openai/gpt-5.5
- openai/gpt-codex-mini  → "GPT Mini" → openai/gpt-5.4-mini
- openai/gpt-pro (new)   → "GPT Pro"  → openai/gpt-5.5-pro

Same relabel + new gpt-pro slug for opencode/* and openrouter/*.
gpt-5.5 (and gpt-5.5-pro) hit the OpenAI public API on 2026-04-24,
day after launch — both are live on OpenRouter as well.

There's no gpt-5.5-mini yet (analysts speculate late June – mid August
based on the gpt-5.4-mini cycle), so "GPT Mini" stays at gpt-5.4-mini
for now; one-line bump when the smaller variant ships.

Also pick up unrelated upstream catalog drift in the snapshot
(xai/grok-4.3 released 2026-05-01, openrouter/poolside laguna).

* deprecate gpt-codex aliases, mint gpt/gpt-pro/gpt-mini, render terminal alias in UI

The previous commit relabeled gpt-codex/gpt-codex-mini in place ("GPT" /
"GPT Mini") so a single slug carried two different identities. That worked
but was self-contradictory: the slug name no longer described the model.

Switch to the same shape we use for the deepseek V3→V4 transition:

- Mint new live slugs: openai/gpt, openai/gpt-pro, openai/gpt-mini
  (mirrored on opencode/* and openrouter/*)
- Restore honest deprecated state on gpt-codex/gpt-codex-mini —
  displayName "GPT Codex" / "GPT Codex Mini", original 5.3-codex /
  5.1-codex-mini resolves, fallback set to the new gpt / gpt-mini slugs
- resolveCliModel + resolveOpenRouterModel walk the chain (existing
  machinery), so DB rows holding "openai/gpt-codex" transparently route
  to gpt-5.5 with no migration

UI render contract: display sites resolve to the *terminal* alias so a
deprecated stored slug shows the model the user is actually running, not
the historical name. Three call sites updated:

- components/ModelSelector.tsx (dropdown trigger label + provider label)
- action/utils/buildPullfrogFooter.ts (PR-comment "Using `X`" footer)
- action/commands/init.ts ("using model X" startup line)

Promoted internal resolveTerminalAlias → exported resolveDisplayAlias so
all three sites use the same primitive (also re-exported from external.ts
+ internal/index.ts so the Next.js app can import it).

Selectable lists (dropdown options, init picker) still filter on
!a.fallback so deprecated slugs never appear as fresh choices — only
deprecated stored values render.

wiki/model-resolution.md: replaced the muddled "slug names outlive
product names" bullet with a clear decision table for in-place bump
(generational, e.g. Opus 4.6 → 4.7) vs. deprecate+replace (vendor
restructures, e.g. codex → unified GPT, deepseek V3 → V4). Documents
the UI render contract too.

models-live CI matrix will smoke-test all 6 new slugs (gpt, gpt-pro,
gpt-mini × openai/opencode/openrouter) plus the 6 deprecated codex slugs
(which resolve through fallback to the same terminal targets) — 12 jobs
total against real provider APIs.

* wiki: slugs are evergreen, resolves are versioned

Document the slug-naming rule explicitly so future entries don't repeat
the deepseek-chat/deepseek-reasoner mistake (mirroring an upstream's
versioned/product-line-specific ID into the slug). Slugs should track
brand-style tier names that survive major version bumps; embedding
versions is the resolve string's job.
