7be725cc13 fix(security): disposition all 104 code-scanning + dependabot alerts (#375)
Fix the 4 real CodeQL path-injection alerts (open_conventions_pr trusted the
API-settable project.workspace_path with no containment) plus defense-in-depth
segment validation at the get_workspace_path chokepoint. Bump next 16.1.1->16.1.7
and transitive lockfile deps to clear 24 Dependabot alerts. Close the intake
subagent-ban gap: the Claude intake driver still carried the Task tool and the
prompter prompt told it to fan out research subagents, contradicting the
fleet-wide ban. The remaining 47 CodeQL + 29 Dependabot alerts are dismissed on
GitHub with per-alert justifications (guard patterns CodeQL can't model across
call hops; next 16.2.x blocked by the verified tab-hostage router regression).

"""Unit tests for the intake driver loop + event normalization.
SDK-free: the `claude-agent-sdk` message types are stood in by tiny fakes named
the same way `normalize` keys off (`StreamEvent`, `AssistantMessage`, ...), and
the driver loop runs against a fake session/source/sink. The real
`SdkIntakeSession` adapter needs the live `claude` binary and is excluded from
coverage.
