Date undated pages by their first mtime, space out word swaps, add a Dockerfile

Found while wiring Patchwork into moonflowersociety.org:

- a page with no date in its name or frontmatter took the day of the
  first scan as its original date, so starting Patchwork on an existing
  site dated every such page to the deploy; the baseline now uses the
  file's modification time and keeps it on later uploads
- removed words right before inserted ones ran together in feed readers
  and in colored terminal output ("modificationthe day"); they're now
  separated by a space
- Dockerfile: static binary on distroless nonroot, with a data directory
  a fresh volume can inherit
- .gitattributes: LF everywhere, so golden files match on Windows too

Publish revisions as a JSON API, Atom, JSON Feed and terminal text

The store now becomes something readers and sites can use. One build
renders every file; `serve` serves it over HTTP and rebuilds after each
scan that changed something, and `export` writes the same bytes to a
directory.

- render: public model (retracted revisions and removed pages left
  out), the v1 JSON API, Atom and JSON Feed entries marked up with
  <del>/<ins>, and plain or ANSI text for curl
- server: routes for slugs with slashes, .json aliases, ETag and 304,
  JSON errors, /healthz
- export: atomic swap of the output directory
- engine: retract (later diffs are rebased), amend, rebuild-diffs,
  backfill of older copies
- schema/v1: strict JSON Schema for the API, checked against every
  generated file
- cli: serve, export, retract, amend, snapshot, rebuild-diffs, backup,
  health
- excerpts sum up long runs of deleted blocks, so a rewrite's new text
  isn't cut off

Snapshot content folders and decide which edits become revisions

Patchwork keeps the version history of pages that keep changing and
publishes the revisions an author announces with a frontmatter note.
This first commit is the core, with no feeds or HTTP yet.

- slug: the moonflowersociety.org rule, checked against a parity table
  generated by the site's own JavaScript
- doc: normalization, frontmatter, ignore regions, block splitting,
  plain text per block, word tokens, content hashes
- diff: Myers on blocks and words, moves, modify pairing, excerpts
- store: SQLite schema and migrations (pure Go, no cgo)
- config: patchwork.yaml with defaults and env overrides
- engine: baseline, silent, published, amended and folded revisions,
  two-scan removal
- source/folder: scans with an upload settle time, watch with file
  events, debounce and polling
- cli: init, scan, watch, log, diff, doctor, version
