v0.5.0

v0.5.0 — per-file blame, commit history, and pinned file views

Major additions:

• Per-file history and blame: commit history strip and Code/Blame tab switcher
  for files in git-backed repos; /api/git/blame and path-filtered commits
  added on the backend.
• Markdown three-tab view: Preview / Code / Blame tabs in the file viewer for
  markdown files.
• File pinned to a commit: diff-card filenames link to the file at that commit;
  ?ref= accepted by /api/meta, /raw/, and /api/git/blame.

Also adds visible gutter dividers and background tinting across all
code-viewing surfaces, fixes mobile diff sticky mis-alignment, and polishes
the file-last-commit strip.

v0.4.0

v0.4.0 — read-only git surface, settings popover, line-number gutters

Major additions:
- Read-only git surface: new git-reader capability exposes branches, commits,
  diffs, and blob history via HTTP API, with corresponding SPA views.
- Settings popover consolidates global preferences (theme, wrap) and a
  two-row desktop toolbar reorganises navigation actions.
- Line-number gutters in the file viewer and diff hunks for easier reading.

Fixes:
- Copy link now works on non-secure HTTP origins (clipboard API fallback).

Also refreshes README (trimmed archive section, updated go install example)
and restructures the OpenSpec capability layout.

v0.3.0

v0.3.0 — file viewer wrap/no-wrap toggle

Adds a wrap toggle to the file viewer so readers can switch between line
wrapping (today's default) and horizontal scroll for code where indentation
matters. Choice persists across files via localStorage. Mobile keeps the
existing 32x32 icon-button footprint.

Also fixes an over-broad dist/ rule in .gitignore that was accidentally
ignoring the SPA build output.

v0.2.0

Initial prebuilt binary release
