fix: retry project detection when agent output has no JSON - #1305

Brings in the eight main fixes since beccc79 (#1275, #1280, #1284, #1294,
#1295, #1301, #1302, #1305). One conflict: agentic detection keeps main's
two-attempt retry loop from #1305 and adds A1's progress emitter to the
agent it initializes.

Brings the final Release A into B1: main through #1305, the per-request
ask signal, host-owned terminal analytics with the flush guard, and A3's
explicit failure status, fatal-path funnel events and linear run
cancellation.

Four conflicts, each resolved to A3's content at B1's program paths:
- the agent README paragraph that names the adapter;
- the import blocks of the adapter test and the project-scope test;
- #1305's new detection retry test, which lands in the renamed
  src/programs/detection/__tests__ and imports @programs/detection/agentic.

#1305's timeout entry lands in the renamed src/agent/error-map.ts.

…book

- Two agent entry comments said the bindings leave in B1. B1 deferred
  PROGRAM_BINDINGS to B2, so they say B2.
- The shared README said claude-settings.ts and errors/agent-map.ts import
  agent leaf modules. Neither does any more. The one agent import left in
  shared is the type-only InstallSkillResult in errors/skill-map.ts.
- The agentic detection runbook cited the removed
  AGENTIC_DETECTION_TIMEOUT_MS. Since #1305 the scan gets two attempts, 60s
  then 90s.

Brings the final Release A, through the new B1, into the callable program
host. B2's structure stays; A's agent contract holds throughout:
- asks and task notices take { signal }, and cancelAsk, cancelTaskNotice
  and cancelQuestion are gone;
- the linear sequence owns a run controller;
- the orchestrator's fatal path reports blocked tasks;
- the agent never sends terminal analytics.

The adapter calls wizardAbort with an explicit status: 'cancelled' only when
the host cancelled, 'error' otherwise. After a non-composed success it sends
'success' behind the flush guard.

main's fixes land where B2 moved the code:
- #1284's warehouse seed cap goes into posthog-integration/run.ts;
- #1280's scan step goes into B2's downloadSkill;
- #1305's two detection attempts share one inference-auth provider;
- the #1305 timer and B2's host-abort check sit side by side in
  agent-interface.

B2's skill-cleanup test now expects an agent [ABORT] to end as failed, and
its host-abort test checks that an unmarked user skill survives.

Brings the final Release A, through B1 and B2, into B3.

What landed in the renamed adapter, src/lib/runners/run-program-agent.ts
(git followed the rename):
- B2's runLegacyStep;
- the explicit wizardAbort status;
- 'success' sent behind the flush guard.

Detection keeps #1305's two attempts, with one inference-auth provider, plus
B3's host context. project-scope uses #1305's timeout handling through B3's
host. B3-11 is also in this merge: the dead AgenticDetectOptions.inferenceAuth
option is deleted, and a test checks that both attempts share the host's
progress and provider.

Seven conflicts, all resolved to both sides' intent.

Carries the final Release A branch, which now includes main's #1319,
#1235, #1305 and 2.77.0. Tests the merge added under src/lib/programs
move to src/programs with B1 import paths.
