docs: adopt anti-rot debt ledger and ADR directory

[alawein]

Adopt anti-rot artifacts

Adds docs/DEBT.md (technical-debt ledger) and docs/adr/ (Architecture Decision Records) per the alawein anti-rot primitives standard. See alawein/alawein docs/governance/anti-rot.md.

Docs-only change. Satisfies the new validate-repo-framework anti-rot check that requires these artifacts in code-archetype repos. Part of the Phase 7 fleet rollout.

Note

Low Risk
Documentation-only changes with no runtime, auth, or deployment behavior impact.

Overview
Introduces anti-rot documentation primitives so the repo can satisfy fleet validate-repo-framework checks: an empty docs/DEBT.md ledger (entry format + /debt-log workflow) and docs/adr/0000-template.md as the starting point for append-only ADRs.

docs/deployment.md is rewritten from placeholder TODOs into guidance that Fallax is local-only (no deploy pipeline): uv install/run examples for eval and baseline commands, provider API key env vars, optional local dashboard, and semver/tagging notes.

docs/troubleshooting.md drops the top-level TODO stub; the existing CRLF/git status section is unchanged.
