chore(deps): bump infer CLI v0.225.0 -> v0.226.0

[inference-gateway-maintainer]

Summary

Centralized-config changes in one PR:

1. Adds/updates .github/workflows/infer.yml as a thin caller of the org reusable workflow
   inference-gateway/.github/.github/workflows/infer.yml@main,
   wiring the @infer bot (inference-gateway/infer-action) into this repo.
2. Bumps this repo's Flox infer pin (.flox/env/manifest.toml) to
   v0.226.0 (the latest inference-gateway/cli release) and
   refreshes .flox/env/manifest.lock.

Setup lives centrally, so future moves (action bump, model, tool scope, CLI version) are a
re-run of migrate-infer.yml instead of a hand-edit per repo.

Ran in CI (mirrors migrate-claude.yml):

• sed the inference-gateway/cli pin in .flox/env/manifest.toml to the latest release
• reconcile schema-version with the flox version this workflow installs (flox never migrates it itself)
• flox upgrade infer + flox activate -- true to refresh .flox/env/manifest.lock in canonical form

Notes

• Triggers on @infer mentions in issues / issue comments. Default model
  ollama_cloud/glm-5.3-flash (override per repo via orchestrators.infer.model in
  repos.yaml). The infer-action pin lives in the reusable infer.yml.
• Also adds a manual workflow_dispatch form: from this repo's Actions tab pick Infer,
  type a free-text prompt (optionally a model as provider/model), and the bot works it
  in that run and opens a PR (no issue needed) - mirroring the @claude workflow.
• Tools = infer-action's default bash whitelist + the language preset (+ markdownlint where
  set), configured in repos.yaml (the entry's orchestrators.infer block).
• Requires the maintainer GitHub App (INFERENCE_GATEWAY_MAINTAINER_APP_CLIENT_ID /
  INFERENCE_GATEWAY_MAINTAINER_APP_PRIVATE_KEY) installed on this repo plus the provider
  API-key secrets; both reach the reusable workflow via secrets: inherit.
