Why: attachments were hard-truncated at 16k chars (most of a meeting
transcript silently dropped), injection carried no task guidance, the
builtin profile prompt was one generic line, subagents were capped at
300 chars, and docx tables were appended after all paragraphs losing
document order - together these produced sparse meeting minutes.
Evidence: go test ./... 16 packages ok incl. new ctxasm limit tests and
docx order assertions (heading->para->table->para); composite make test
green over the pinned combo.
Impact: attachment ceiling is 48k chars (settings
context.maxAttachmentChars), truncated on rune boundaries and observable
in the context report; the builtin prompt demands full-coverage
structured markdown for document tasks and upgrades stale builtin rows
on boot; budget.maxTokens now reaches the provider; subagents may write
full-length results; docx tables stay in place.
