Incrementally make Panache's CST shape for HTML-block /

Grow Panache's CommonMark spec conformance under `Flavor::CommonMark` by running every `spec.txt` example through the shared parser, comparing rendered HTML against the spec's expected HTML (byte-equality after `<li>` whitespace normalization), and triaging failures into renderer / parser-shape / flavor-leak / dialect-divergence / missing-feature buckets. Use when asked to advance the CommonMark pass rate, grow the allowlist, or unblock a CommonMark regression.

Incrementally migrate Panache's Pandoc-dialect inline parsing onto the unified inline IR (currently CommonMark-only) one bounded sub-task at a time, verifying every CST divergence against pandoc-native before fixing or deferring.

Add a new built-in lint rule to the Panache linter — wire it into the registry, gate it on the right extension/flavor, add a regression fixture with focused assertions, and document it.

Incrementally build Panache's math parser and formatter — a lossless structural TeX CST for inline/display math, then content-aware reformatting behind an experimental gate — one bounded phase at a time.

Triage and fix panache smoke-test regressions (idempotency, losslessness, parse/format checks) from CI debug-format reports and linked issues.

Profile-driven performance work on the panache parser or formatter. Measure first with perf + the right harness; classify hotspots into one of a small set of buckets; apply the matching cheap fix; verify median wall-time moved before committing.
