chore(licence): clear residual PMPL debt after the MPL-2.0 ruling

[hyperpolymath]

Follow-up to #78 (owner ruling: MPL-2.0 for code, CC-BY-SA-4.0 for docs). Clears the four residue items fenced in the #78 report, all owner-approved:

• Delete vext/COMMIT-AND-PUSH.sh — legacy one-shot bootstrap script with broken /var$REPOS_DIR / /var$HOME paths, superseded by the monorepo. grep -rn 'COMMIT-AND-PUSH' proves no inbound references.
• Fix vext/vext-core/Cargo.toml cargo-deb pointer — license-file pointed at ../LICENSE.txt, which never existed; now ../LICENSE (canonical MPL-2.0 since fix(licence): apply owner ruling — MPL-2.0 for code, CC-BY-SA-4.0 for docs #78). [package] license = "MPL-2.0" was already correct and is untouched.
• Drop the dead PMPL alternative from the licence-content accept patterns in contractile.just:65 and .machine_readable/contractiles/Trustfile.a2ml:57. Behaviour-neutral (MPL substring-matched PMPL anyway); the patterns now name only licences that can actually appear.

Verification: just trust-verify and just trust-manifest-verify both pass locally; all 8 component manifests verify unchanged, so no regen is required (neither gate file is manifest-tracked). No uses: refs touched, so actions.lock is untouched per the standing contract.

📝 Summary

Summary by CodeRabbit

• Bug Fixes

  • Corrected licence validation so only supported identifiers are accepted, preventing the erroneous PMPL match.
  • Updated Debian package metadata to reference the correct LICENSE file.

• Chores

  • Removed an obsolete script used for automated repository commits and publishing.

Walkthrough

The change corrects licence identifier patterns in two checks, updates Debian package metadata to use LICENSE, and removes the Vext commit-and-push script.

Changes

Licence validation and packaging

Layer / File(s)	Summary
Correct licence pattern matching .machine_readable/contractiles/Trustfile.a2ml, contractile.just	The licence checks no longer match PMPL. They retain the supported licence identifiers.
Vext packaging metadata vext/vext-core/Cargo.toml	The Debian package now references ../LICENSE instead of ../LICENSE.txt.
Vext script removal vext/COMMIT-AND-PUSH.sh	The repository no longer contains the script that prepared, committed, and pushed Vext changes.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to adc17

The PR updates license validation patterns, but the current head still permits invalid PMPL matches and leaves the two validation checks inconsistent, which can accept unrelated license text or reject LGPL; merge should wait for bounded, aligned patterns.

A rabbit checks the licence line
No PMPL mark remains to find
The package points to LICENSE clear
The old push script disappears

.machine_readable/contractiles/Trustfile.a2ml lines 57-57 and contractile.just
lines 65-65 to use boundary-aware patterns for every alternative: MPL, MIT,
Apache, and LGPL. Ensure invalid embedded identifiers such as PMPL are rejected;
both sites require direct changes.

In `@contractile.just`:
- Line 65: Align the trust-license validation in contractile.just with
.machine_readable/contractiles/Trustfile.a2ml: accept LGPL alongside MPL, MIT,
and Apache, and remove the overly broad SPDX and License matches. Update the
generator source or regenerate the generated Trustfile so both definitions use
the same license-content criteria.

No change required. ../LICENSE resolves to the intended vext/LICENSE file for the Debian package.

Review triage (both findings accepted and fixed in cae5404):

1. Unbounded MPL accepts PMPL — confirmed empirically: both pre-fix patterns passed a synthetic PMPL licence body (exit 0), i.e. the gates were vacuous against the exact identifier this PR retires.
2. SPDX|License over-broad in contractile.just — accepted; License matches virtually any licence file, making the gate unable to fail.

Both gates now use the aligned boundary-aware pattern grep -qE '\b(MPL|MIT|Apache|LGPL)\b' LICENSE. Verified both directions: matches the canonical MPL-2.0 body (bounded MPL occurs in Exhibit A's mozilla.org/MPL/2.0/ URL) and rejects PMPL text (exit 1). just trust-verify + just trust-manifest-verify green; neither file is manifest-tracked, so no regen.

Out of scope here: per-component contractiles/trust/Trustfile.a2ml license-content patterns (no PMPL alternatives there; aligning them to the bounded form would dirty 8 trust manifests and belongs in a dedicated pass if wanted).
