[P3 carryover] Align HTML IPC injectable request type with Fast mode

[project820]

Carryover from PR #68

PR #68 (f2f7366, merged) wires the HTML-only GPT Fast mode through the renderer, IPC boundary, transport, and provider registry.

Residual issue

src/main/ipc/html-export-ipc.ts:72-80 defines the injectable generateHtml input without reasoningEffort?: 'low'.

The live request uses a spread and currently forwards the field correctly, as covered by the focused tests. However, a future field-by-field implementation constrained by this type could silently omit Fast mode.

Desired fix

Align the injectable generateHtml request type with the public html:generate request shape by adding the optional 'low' reasoning effort field. Keep the Fast forwarding test and update its stale title if applicable.

🤖 Psycho-842 [BOT] triage

ℹ️ TRIAGE — The public IPC request accepts Fast mode, but the injectable generation seam does not declare it.

Summary

isGenerateRequest() accepts reasoningEffort?: 'low' for the curated ChatGPT HTML models, while HtmlExportIpcDeps.generateHtml omits that optional field.
The current production generator declares and forwards the field, so this is a maintenance-contract gap rather than a measured runtime failure.

Reproducibility & Evidence

Measured on main at 57c04f25464726a8035627977995877193daea17: src/main/ipc/html-export-ipc.ts:245-277 validates and returns a request type containing reasoningEffort?: 'low', but the injectable callback input at lines 72-80 lacks it. src/main/html-export-generate.ts:32-39,94-101 declares the field and forwards it to the transport. The focused IPC test covers cloud and local requests but its exercised cloud request omits Fast; no local test was run in this triage.

Impact & Priority Suggestion

• 🟡 P3 Low — Add reasoningEffort?: 'low' to the injectable callback input and exercise that injected seam. This prevents a future field-by-field test double or implementation from dropping Fast without a type-level prompt.

Duplicates & Related

Related, not duplicate: merged PR #68 introduced the Fast path; closed issue #65 requested it. Open issue #66 is a separate residual batch. No other known duplicate was found in the repository issue/PR search.

Next Evidence Needed

• Add or update a focused IPC test that sends reasoningEffort: 'low' for an allowed GPT HTML model and asserts the injected generator receives it.
• Confirm the test title describes the Fast-forwarding behavior if it changes.
