refactor: clear the rest of the lint backlog and make `make lint' actually work

Took the package-lint commit's foundation and finished the job. Three
groups of changes:

1. **checkdoc** is now clean across all three package files. I worked
   through every warning: 13 missing-double-space-after-period fixes, 4
   message-capitalization fixes, 1 trailing-period-on-error fix, 6
   Lisp-symbol-should-be-quoted fixes, and one rephrase from "starts" to
   the imperative "Log the start of an async check". One `chime-debug.el'
   docstring also exceeded 80 columns and got split into two lines.

2. **`make lint'** ran elisp-lint but had been silently broken. The shell
   glob `test-*.el' wasn't expanding (CWD ended up at project root, not
   tests/), and the noisy validators flagged everything. I rewrote the
   target to lint package files explicitly via absolute paths, preload
   chime.el so the byte-compiler sees cross-file symbols when checking
   chime-debug.el, and disable the validators that conflict with project
   style or duplicate other lint steps:
   - `--no-checkdoc' (covered by `eask lint checkdoc')
   - `--no-package-lint' (covered by `eask lint package'; running it on
     auxiliary files re-flags them as standalone packages)
   - `--no-indent-character' (project uses spaces per
     `.claude/rules/elisp.md'; the validator defaults to tabs)
   - `--no-fill-column' (project allows up to 80; validator defaults to 70)
   - `--no-indent' (false-positives on dash threading macros `->'/`->>')
   The validators-disabled list is documented in the recipe header.

3. **Generated autoload files** (`chime-autoloads.el',
   `tests/tests-autoloads.el') are now gitignored. `tests/tests-autoloads.el'
   was tracked from an earlier commit; I removed it from the index.
   Eask regenerates these on every `eask compile' / `eask install-deps'
   run, so they don't belong in the tree.

Verified: `make compile' clean (with byte-compile-error-on-warn t),
`make test-all' green at 677 tests, `eask lint package' clean,
`eask lint checkdoc' clean, `make lint' clean. Full lint backlog is now
zero across all three checks.
