fix(go): paginate multi-match results instead of dropping them

[baanish]

Problem

qr go <query> ranked every match, then silently kept only the first 9. The numbered picker already knew how to page, but callers never received more than one page. A common query like vibe could hide later projects (and nested dirs) with no indication that more existed.

Change

• Return the full ranked match list (including typo/bigram fallback).
• Keep 1–9 keypress selection, 9 results per page.
• Show the total count and current page (Page 2/3 (10-18 of 24)).
• Page with ←/→, ↑/↓, PageUp/PageDown, or n/p.

Demo

qr go vibe with 15 cached matches: page 1 (1–9), n to page 2, p back, then 1 selects vibe-09.

Verification

• cargo test — including ranking/pagination unit tests and a CLI test that a 15-project query lists every name.
• cargo clippy --all-targets --locked -- -D warnings — clean.
• Interactive PTY/desktop picker: page 1 shows 1–9, n shows 10–15, 1 on page 2 selects /tmp/qr-paginate-demo/projects/vibe-09.

📝 Walkthrough

Walkthrough

qr go now keeps all matching projects instead of limiting results to nine. The numbered picker paginates results, supports bounded navigation, and displays page and match counts. Tests cover matching, picker behavior, and noninteractive CLI output.

Changes

Project match pagination

Layer / File(s)	Summary
Complete match collection src/commands/go.rs	rank_matches returns all substring and bigram-fallback matches. Regression coverage verifies 15 matching projects are retained.
Paginated numbered picker src/picker.rs, tests/cli.rs, CHANGELOG.md	The picker uses a shared page size, validates selections, supports arrow, PageUp/PageDown, n, and p navigation, and displays pagination status. Unit and CLI tests cover the new behavior. The changelog records the updated interaction.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 6276d

Pagination works, but the picker and changelog omit some supported navigation keys, so users may not discover all ways to move between pages. The PR is mergeable with explicit follow-up to document those controls.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Incremental review of the change since 6276dec:

• src/picker.rs:255 hint now lists all supported pagination controls (←/→ ↑/↓ PgUp/PgDn or n/p), matching the actual KeyCode handling at src/picker.rs:182-195.
• src/picker.rs:639 test expectation updated to match the new hint string.
• CHANGELOG.md:23 documents all supported pagination controls.

This resolves the previously active inline finding at src/picker.rs:264 (list all supported page-navigation controls). The source hint, the unit test string, and the changelog are consistent, and the text accurately reflects the implemented key handling.

Status: No Issues Found | Recommendation: Merge

Reviewed this pagination change end-to-end: the pages/offsets math in the numbered picker (page count, page range, absolute index, next/previous page clamping), the single-digit 1-9 selection contract per page, the header/hint strings, and the regression tests in both rank_matches (unit) and the non-interactive CLI path.
