v1.8.3

v1.8.3 — Fix TUI layout

Root cause

Three independent bugs in the TUI rendering pipeline:

1. Header scrolling off screen — the title/column header row was rendered as part of the scrollable content instead of being anchored before the scroll region.
2. Footer floating up — when the result list was shorter than the terminal height, the keyboard-shortcut bar moved up into the results area instead of staying pinned to the last row.
3. Narrow-terminal clipping corrupting multi-byte characters — clipAnsi advanced byte-by-byte, splitting surrogate pairs / emoji at a raw byte boundary and producing garbled output.

Changes

• src/render.ts — header anchored above scroll region; footer preceded by blank-line padding (for (let i = usedLines; i < viewportHeight; i++) lines.push("")) to fill the viewport; clipAnsi now iterates with codePointAt to advance by full Unicode code points and appends \x1b[22;39m (partial reset preserving background) instead of a full \x1b[0m; maxPathVisible and maxLeftVisible floors lowered to Math.max(1, ...); section label maxLabelChars floor lowered to Math.max(0, ...) with blank-line placeholders when 0.
• src/render/rows.ts — new normalizeScrollOffset() pure function that decreases the scroll offset when the current position leaves blank space at the bottom of the viewport.
• src/tui.ts — normalizeScrollOffset called in a fixed-point loop inside redraw() so the offset always fills the screen; getRepoRowIndexMap lazy O(1) Map replacing O(n) findIndex; title badge now renders as pc.bgMagenta(pc.black(pc.bold(...))) for maximum contrast.
• docs/blog/release-v1-8-3.md + docs/blog/index.md + CHANGELOG.md — release notes.

Steps to reproduce (before the fix)

# On a terminal tall enough to show blank space below results:
github-code-search query "foo" --org myorg
# → scroll down: header disappears  
# → on a short result set: footer floats above the last line
# → on a narrow terminal with emoji in paths: garbled characters

Steps to verify (after the fix)

bun test          # 567 pass, 0 fail
bun run lint      # zero errors
bun run format:check
bun run knip
bun run build.ts

Closes #105

The PR description lists substantial changes in src/render.ts, src/render/rows.ts, and src/tui.ts, but this PR’s diff only shows a version bump + docs/changelog updates. Either include the missing source-code changes in this PR, or update the PR title/description so it accurately reflects what’s being merged.
