fix(licence): correct AGPL declarations to MPL-2.0 (owner-authorized) (#45)

The repo's metadata declared `AGPL-3.0-or-later` as the project licence in
seven places, contradicting its actual licence (the root `LICENSE` is MPL-2.0
text, `LICENSES/` holds MPL-2.0 + CC-BY-SA-4.0) and its own AGENTIC policy
("Never use AGPL license (use MPL-2.0)"). The 2026-05-26 tech-debt audit
already recorded this as licence debt.

Owner (hyperpolymath) explicitly authorized the correction: SPDX → MPL-2.0
for the repo, CC-BY-SA-4.0 for docs. This satisfies the manual/owner-only
requirement for licence edits.

Corrected the authoritative declarations, swapping only AGPL → MPL-2.0 and
preserving the existing `LicenseRef-Palimpsest-0.5` dual-license structure:
- CITATION.cff `license:` (and `license-url:` LICENSE.txt → LICENSE)
- codemeta.json `license:`
- .well-known/dc.xml `<rights>` + `<dcterms:license>`
- META.scm `license-compliance` + the `why-agpl` rationale (now `why-mpl`)
- Containerfile OCI `image.licenses` label
- docs/CITATIONS.adoc BibTeX `license`
- RSR_COMPLIANCE.adoc LICENSE status row

Left as-is intentionally: the root `LICENSE` (already MPL-2.0) and `LICENSES/`
(already correct); the AGENTIC "never AGPL" policy line (correct); and the
historical records that merely describe the past state — the dated
`docs/tech-debt-2026-05-26.md` audit snapshot and the `STATE.scm` change log.
Docs files already carry `SPDX-License-Identifier: CC-BY-SA-4.0` headers.

Licence edits are supervised per doctrine — opening as a draft for owner review.
