feat(cli): persist project-scoped prompt history

[lifelmy]

Summary

Closes #1125.

• persist CLI prompt history per project by default while preserving the existing global history path behind FREEBUFF_HISTORY_SCOPE=global
• cap persisted history at 500 entries by default and collapse consecutive duplicate prompts
• add FREEBUFF_HISTORY_SIZE=0 as an explicit off switch for prompt history persistence
• document the plaintext on-disk history behavior and configuration in the CLI README
• keep recalled entries editable before resubmission through the existing up/down recall flow

Testing

• bun install
• ./node_modules/.bin/prettier --write cli/README.md cli/src/chat.tsx cli/src/hooks/use-input-history.ts cli/src/utils/message-history.ts cli/src/utils/tests/message-history.test.ts
• git diff --check
• bun test cli/src/utils/tests/message-history.test.ts cli/src/hooks/tests/use-input-history.test.ts cli/src/utils/tests/keyboard-actions.test.ts cli/src/utils/tests/chat-input-key-intercept.test.ts — 111 pass, 0 fail, 213 expect() calls
• bun run build:sdk
• bun run build:freebuff

Notes

I also tried the broader CLI checks. cd cli && bun run typecheck currently fails because this checkout is missing existing dependencies/types for tar and react-dom/server; cd cli && bun run test currently fails before running tests because cli/bunfig.toml preloads missing ../test/setup-scm-loader.ts.

I use a coding assistant to help implement, and I review and take responsibility for the final change.

Refreshed this branch onto the latest public main; new head is 15effff45. The merge completed cleanly and only incorporated upstream public snapshot updates. The PR diff remains scoped to project-scoped CLI prompt history and the related docs/tests.

Verification on 15effff45:

• git diff --check -> clean
• bun test cli/src/utils/__tests__/message-history.test.ts cli/src/hooks/__tests__/use-input-history.test.ts cli/src/utils/__tests__/keyboard-actions.test.ts cli/src/utils/__tests__/chat-input-key-intercept.test.ts -> 111 pass / 0 fail
• bun run build:sdk -> build complete
• bun run build:freebuff -> build complete

Broader local CLI checks still hit the same pre-existing environment/dependency gaps as before: cd cli && bun run typecheck is blocked by missing tar and react-dom/server declarations, and cd cli && bun run test is blocked by missing ../test/setup-scm-loader.ts preload.

Refreshed this draft PR onto the latest public main; new head is 83b7cdfdb. The merge completed without manual conflicts and only incorporated the latest upstream public snapshot updates (README*, free-model catalog/constants/tests, and related CLI settings coverage). The project-scoped prompt history diff remains unchanged.

Verification after refresh:

• bun test cli/src/utils/__tests__/message-history.test.ts cli/src/hooks/__tests__/use-input-history.test.ts cli/src/utils/__tests__/keyboard-actions.test.ts cli/src/utils/__tests__/chat-input-key-intercept.test.ts -> 111 pass / 0 fail
• bun run build:sdk -> success
• bun run build:freebuff -> success
• cd cli && bun run typecheck -> still fails in pre-existing workspace files because tar and react-dom/server declarations are missing; no new failures attributable to this PR
