lint: promote 105 safe any patterns to unknown (no-explicit-any −97)

[adm01-debug]

Summary

ESLint: 1939 → 1856 problems (−83). 97 of 257 no-explicit-any violations resolved. No type errors introduced — all 105 mechanical transforms compile cleanly.

scripts/codemod-any-to-unknown.mjs (new)

Targeted codemod that promotes any to unknown only in patterns where the change is mechanical and the narrowing it forces is a net positive:

Pattern	Count	Why it's safe
[key: string]: any	9	Index signature — consumer must narrow before using value
useState<any>	5	React state — narrow on read; setter still accepts anything
as any	20	Cast — as unknown requires a 2nd cast, surfacing the danger zone
Record<string, any>	32	Same as [key: string]: any
Map<K, any>	2	Same
: any[]	37	Array — members must be narrowed before use
Total	105	across 67 files

The codemod pre-strips comments and string literals (replacing them with whitespace, length-preserving) so regex matches don't trigger inside documentation. Replacements applied right-to-left to preserve offsets.

NOT handled (kept as any, tracked as roadmap)

• Bare : any parameter/return/variable annotations (~150 cases). Mechanical promotion to unknown cascades type errors through every consumer; these need contextual review.
• Generic args on RPC helpers (invokeExternalRpc<any>, selectCrmById<any>). These are deliberate "narrow at the call site" markers; bumping them breaks the established API contract.

These belong in dedicated follow-up PRs, ideally one per feature area.

Validation

Metric	Before	After
Total problems	1939	1856
no-explicit-any	257	160
tsc --noEmit	exit 0	exit 0
npm run test failing	10/43 (pre-existing, see PR #28)	10/43 (same)

Counts by pattern:
  index-signature          9
  useState-generic         5
  as-any                   20
  record-string-any        32
  map-value-any            2
  set-any                  0
  any-array-annotation     37
