Release Pinmind 0.9.1 with a real lifecycle split and offline AEP/P2

[iammedved]

Proposal

state.mjs still mixed lock/journal I/O, contract freeze/amend, evidence capture, and run lifecycle. AEP and P2 were documented as if they were current product work while neither changes runtime. Value questions such as «какое улучшение это дало» still became software-change via the улучш stem.

This release:

• splits the kernel along real seams: persist.mjs (lock/journal/I/O), contract.mjs (freeze/amend), evidence.mjs (capture/store), state.mjs (init/report/finalize);
• keeps AEP and P2 off SKILL.md and the kernel, and moves P2 adapters out of the current roadmap;
• classifies value questions about improvement as audit. Imperative улучши / надо улучшить still change software.

Safety checklist

• I removed secrets, credentials, personal data, private URLs, and local absolute paths.
• I included only files needed for this proposal.
• I ran the relevant validation commands.
• I understand that submission does not grant write or merge access and that the maintainer decides whether to apply the change.

Test Plan

• node scripts/verify-release.mjs --run passed locally (ok: true, plugin 0.9.1, 457 route fixtures, 89 declarations, 18 commands).
• GitHub verify workflow on this PR.
