fix(personas): exact tool_use_id pairing + CI drift audit

Two loose ends from M3/M4:

1. Tool_use_id-based error attribution in the persona-runner
-----------------------------------------------------------
The previous collectActionsFromMessage() flipped the *most recent*
ActionRow to 'error' when a tool_result carried is_error:true. That was
fine as long as Claude invoked tools strictly in sequence, but when
the planner pipelines multiple tools in one turn, a later tool_result
carries an earlier tool_use_id — the last-action fallback mis-
attributes the error.

runMainTurn() now keeps a tool_use_id → action-index Map for the
duration of the tick. On tool_use we stash block.id, on tool_result we
look up the exact ActionRow via tool_use_id and flip that one. The
"flip last" path survives as a pure fallback if a future SDK ever
ships a block without an id.

2. New audit:encrypted-tools script
-----------------------------------
scripts/audit-encrypted-tools.ts — loads registerAllModules() and
apps/mana/…/crypto/registry.ts, diffs every ToolSpec.encryptedFields
against the authoritative web-app ENCRYPTION_REGISTRY.

Catches three classes of drift:
- missing-table : tool declares a table the web-app doesn't encrypt
- field-drift   : both agree a table is encrypted but the field lists
                  differ (half-encryption in the wire is silent death)
- disabled      : web-app has enabled:false while the tool still
                  encrypts — advisory warning, not a fail

Negative-tested by injecting a deliberate drift on todo.create +
todo.list (shortened ENCRYPTED_FIELDS to ['title']); the auditor
flagged both tools with full field diffs, restore returned to green.

Wired into `pnpm run validate:all` so the contract survives future
edits on either side. Fills the M4 audit gap noted in
project_mana_mcp_personas.md.
