fix: handle quotes, comments, and indented lines in frontmatter parser

[Tokenized2027]

What

Three surgical fixes to the hand-rolled YAML frontmatter parser in parse_frontmatter() (src/openstation/core.py). Zero new dependencies — stays true to the project's minimal philosophy.

Edge cases fixed

1. Quoted values not unquoted

Before: name: "my-task" → '"my-task"' (quotes included in value)
After: name: "my-task" → 'my-task'

Works for both single and double quotes. Mismatched quotes (opening ≠ closing) are left untouched.

2. Comment lines silently poisoning the fields dict

Before: # this is a comment → key "# this is a comment" added to result
After: comment lines are skipped entirely

3. Indented list items treated as key-value pairs

Before: - subtask-1 → key " - subtask-1" with empty value added to result
After: lines starting with whitespace (space or tab) are skipped — parse_frontmatter_list() handles those separately, as it always has

New tests

tests/test_frontmatter.py — 26 test cases across 7 test classes:

• TestStandardFrontmatter — regression tests for existing behaviour
• TestColonValues — values containing colons (including URLs)
• TestQuotedValues — single quotes, double quotes, mismatched, unquoted
• TestCommentLines — full-line comments skipped, inline comments preserved
• TestIndentedLines — space-indented and tab-indented lines skipped
• TestEmptyFrontmatter — empty block, comment-only, blank-line-only
• TestRealisticFrontmatter — full task and agent spec fixtures

Test results

All existing 416 tests pass. 26 new tests added, all passing.

(The 5 pre-existing failures in test_hooks.py are Windows shell-environment issues unrelated to this change — they fail identically on main.)

Hey, thanks for the contribution! The diff looks larger than expected because the file was converted from LF to CRLF (Windows line endings) — every line shows as changed even though only a few lines actually differ.

Could you normalize the line endings back to LF? This should work on any OS:

git config core.autocrlf input
git rm --cached src/openstation/core.py
git add src/openstation/core.py
git commit -m "fix: normalize line endings to LF"

Also, if you're up for it, it'd be great to add a .gitattributes file to the repo root to prevent this from happening again:

* text=auto eol=lf

Once that's done the diff should be clean and easy to review. Thanks!

Merged manually into main via commit 05edca2. Applied the three parser fixes and 26 new tests with clean LF line endings (avoiding the CRLF whole-file diff). Added .gitattributes to prevent future line-ending issues. Thanks for the contribution!
