Let advisors recover truncated review context

[fcakyon]

Both advisors refused to review instead of ruling: the hooks shredded tool output, then the prompts banned the file reads that could have recovered it.

	before	after
tool_use cap	280	8000
tool_result cap	700	8000
context used of 160k budget	22,365	115,845

• reviewers get read-only access, so they grep what the window drops
• the 80-record cutoff now announces itself instead of passing silently
• fable blocked reads in two more places: tools: [] and --tools ""

-return `  ↳ result: ${clip(text, 700)}`;
+return `  ↳ result: ${clip(text, 8000)}`;
+if (i >= 0) recent = `…[this is only the newest ${records.length} turns of a longer session]\n` + recent;
