abcd intent writes free text with no redaction, so a home path is committed

[jogrun]

What

abcd capture redacts committed prose (iss-2608231025198888). abcd intent "<text>" does not.

CreateFromText stores the caller's text as title and body verbatim:

• internal/core/intent/create.go:41-55 — SeedBody: trimmed, Title: titleLine(trimmed)
• internal/core/intent/create.go:250-254 — seedDraft writes # + title and ## Why This Matters + SeedBody with no scanner pass

There is no redact symbol under internal/core/intent/. Capture's redactLedgerText (internal/core/capture/redact.go:29) is the sibling that already does this for the issue ledger.

abcd intent "fix /Users/alice/.ssh/id_rsa leftover in the install receipt"

commits that path under .abcd/development/intents/drafts/itd-N-….md.

deriveIntentSlug (create.go:152) kebab-cases the same way capture's CLI does, so the filename can pick up users-alice-… as well (same shape as the capture-slug leak).

Suggested fix

Run the capture redactor (or a shared helper) on title and SeedBody before CreateDraft. Add a test that CreateFromText with $HOME in the text writes no home root into the draft file. Watch it fail on main.

Happy to send a PR once this is accepted.
