Rebase reconciliation: fold main's post-freeze work into the swapped tree

The rebase onto origin/main brought changes whose JS engine halves left the
tree with the swap. This commit reconciles what survives:

- Suite map: register main's comp-fidelity unit tests (build-phase,
  comp-diff, font-match, hero-checks) in the core suite and
  live-browser-ignores in the live suite.
- Payload guard: the skill scripts payload now allowlists the comp-fidelity
  build pipeline (comp-spec/comp-diff/build-phase/font-match and their libs),
  the one Node toolchain that has not moved into the engine.
- Drop skill/scripts/live/project-ignores.mjs, lib/live-path-globs.mjs, and
  their test: they import hook-lib/live-inject/impeccable-paths, which the
  swap deleted, and their consumer (the JS live server) is the engine now.
- skill text: the comp pipeline's calls to engine verbs (generate-image,
  embed-prompt) use the launcher spelling.
- Oracle: re-record 17 detect goldens over the fixture set main changed
  (oklch #592, color-mix #578, 1D grid #615, the two comp-fidelity rules)
  and record the gap in DELTAS.md; those JS rule changes are not yet ported
  to the engine, and the goldens pin its current behavior.

bun run test (oracle included) and bun run build are green on this tree.

AI-assisted change: implemented with Claude Code.

+## Recorded 2026-08-31: main's post-freeze fixture changes, goldens re-recorded from the engine
+
+The rebase onto main brought fixture updates whose paired JS rule changes have
+not been ported to the engine yet. The detect goldens below are re-recorded
+from the binary, so they pin the engine's current behavior on the new fixture
+content; the entries name the upstream JS change each one still owes. Until a
+rule ships in the engine and its golden is re-recorded, the golden is the pin
+of the gap, not an endorsement of it.
+
+- `detect-fixture-json-color-html`, `detect-fixture-text-color-html`: the fixture gained the color-mix nested-hex column (upstream 54440319, #578, with explicit sizes from 7426af44); the engine still reads hex codes inside `color-mix(...)` when measuring gradient contrast, so its readings on the reshaped fixture differ from the JS engine's.
+- `detect-fixture-json-oklch-neon-text-html`, `detect-fixture-text-oklch-neon-text-html`: new fixture for oklch parsing in visual-contrast and neon-text (upstream 1b7da15b, #592, columns from 8347d77f); the engine does not parse oklch there yet, so the flag column's neon-text goes unflagged and a mis-read low-contrast is recorded.
+- `detect-fixture-json-codex-grid-1d-pass-html`, `detect-fixture-text-codex-grid-1d-pass-html`: new pass-case fixture for 1D dashed rules (upstream a236137b/7ddcd533, #615); the engine still flags the 1D line-field as `codex-grid-background`, which is the pre-fix behavior the fixture exists to retire.
+- `detect-fixture-json-organic-clip-path-html`, `detect-fixture-text-organic-clip-path-html`, `detect-fixture-json-buried-raster-html`, `detect-fixture-text-buried-raster-html`: fixtures for the two comp-fidelity rules (upstream 58561610: organic-clip-path, buried-raster); neither rule exists in the engine, so only incidental findings (or none) are recorded.
+- `detect-dir-json-all-fixtures`, `detect-dir-text-all-fixtures`, `detect-dir-quiet-all-fixtures`, `detect-scope-type`, `detect-scope-both`, `detect-no-advisory-json`, `detect-no-advisory-text`: directory-wide sweeps over `tests/fixtures/antipatterns/`; re-recorded because the fixture set above grew and changed, shifting counts and orderings.
