docs: auto-update for merged PRs (2026-09-08)

[aheritier]

Updates /docs to reflect behavior changes from PRs merged into main in the last 36 hours that were not already covered by doc updates in their own PR.

Changes

• Lean TUI: document the new /copy command (source: feat: add copy command to lean TUI #4188)

  • docs/features/tui/index.md: added /copy to the list of slash commands supported by the lean TUI, and noted that it copies the last assistant response to the clipboard.

• SSRF pre-check DNS lookup: document the bounded timeout / fall-open-on-timeout behavior (source: fix(http): bound the SSRF pre-check DNS lookup in desktopAwareTransport #4186)

  • docs/tools/fetch/index.md, docs/tools/api/index.md, docs/tools/openapi/index.md: the Docker Desktop PAC-routing preflight description previously stated that all DNS lookup failures keep a request on the direct SSRF-guarded path. That's no longer accurate — the lookup is now bounded to 2 seconds, and if it times out (while the request's own context is still live) resolution falls through to Docker Desktop routing instead of blocking indefinitely. NXDOMAIN, empty results, other resolver errors, and private/mixed answers are unaffected and still fail closed onto the direct path. Updated the wording in all three affected docs to match.

PRs reviewed with no doc changes needed

• fix: account for long-context tiers and fallback model pricing #4189 (long-context tier / fallback pricing fix) — already ships its own doc update in docs/configuration/models/index.md, verified accurate and complete.
• fix: harden concurrent and external resource handling #4185 (concurrency/resource hardening) — already ships its own doc update in docs/concepts/distribution/index.md; the rest of the change is internal robustness work with no user-facing/documented contract change.
• docs: fix inaccuracies across SDK examples, CLI flags, telemetry, permissions, and integrations #4184 (docs-only PR) — no further action needed.
• chore: refresh models.dev snapshot (+129 -67 ~322) #4183 (models.dev snapshot refresh) — docs/providers/github-copilot/index.md already reflects the current example model.
• docs: auto-update for merged PRs (2026-09-05) #4178 (previous docs auto-update PR) — already merged.
• fix(config): hint at removed fields instead of re-adding them #4177 (removed-field config hint) — already ships accurate doc updates in docs/configuration/overview/index.md and docs/tools/shell/index.md.
• feat(eval): pin injected docker-agent image to host CLI version by default #4176 (eval: pin agent image to CLI version) — already ships accurate doc updates in docs/features/cli/index.md and docs/features/evaluation/index.md.
• docs: update CHANGELOG.md for v1.134.0 #4187 (CHANGELOG only) — no /docs impact.
