Machine-readable currency: deferred follow-ups (post-checkpoint #115)

[hyperpolymath]

Deferred items from the machine-readable / contractile currency checkpoint (PR #115).

burble-specific

• trust/Trustfille.a2ml — typo filename holding ~900 lines of example.com template content; remove via dust sweep --apply.
• bust/Bustfile.a2ml — non-gold Bust { } schema (meta-repo rollback scenarios); rewrite to gold ## Section / ### check shape with burble-specific probes.
• svc/k9/examples/setup-repo.k9.ncl references deprecated PMPL-1.0 — owner review.

Estate-common

• Contractile k9.ncl + manifest tridents for must/trust/bust/dust (canonical only ships them for adjust/intend).
• ANCHOR placement normalization vs rsr-template.
• Per-bot bot_directives/ content: hypatia, gitbot-fleet, .git-private-farm.
• Workflow hygiene: missing_timeout_minutes / unpinned_action (Hypatia baseline).
• License review (owner): AGPL/PMPL stamps in .machine_readable/ — flag-only, no edits made.
• Wiki refresh.

Root cause

RSR-SPEC.adoc v1.0.0 (frozen 2025-12-27) never bumped for post-2026-04 policy → spec-conformant but policy-stale. Owner: cut RSR-SPEC v1.1/v2.0 + re-sync rsr-template-repo.
