* fix(daemon): tighten quick-create prompt to drop meta-instructions and apologetic Context

The quick-create prompt was producing descriptions that:
1. Echoed routing meta-instructions ("create an issue for me", "cc @X") into
   the User request body, even though those phrases are handled by separate
   CLI flags and are not spec content.
2. Emitted a Context section to apologize for resources it could not fetch
   (e.g. an image attachment not piped through to the run), instead of
   staying silent and letting the executing agent ask the user.
3. Preserved pure conversational fillers ("对吧?", "嗯", "那个…") because the
   model treated removing them as forbidden paraphrasing.

Updates the prompt to call out each of these as explicit non-spec material
to strip before writing the description, while keeping the "high fidelity /
no paraphrasing of substantive content" invariant. Adds a regression test
that locks in the new rules at the substring level.

* fix(daemon): preserve cc mention links in quick-create description

Stripping "cc @Y" wholesale would have lost the mentioned member's only
routing channel: `multica issue create` has no --subscriber/--cc flag, and
the platform auto-subscribes members by parsing `[@Name](mention://member/<uuid>)`
links from the description body. Without the mention link in the body, a
cc'd member would never get subscribed or notified.

Updates the prompt to:
- Strip only the verbal "cc" wrapper from the User request body.
- Append a trailing `CC: <mention links>` line to the description so the
  platform's auto-subscribe logic still picks the mentions up.
- Spell out the contrast for assignee mentions, where --assignee-id is
  the routing channel and the body should not double-encode the mention.

Also adds a substring assertion for the "Pure conversational fillers" rule
that was missing from the original regression test.

* refactor(daemon): trim quick-create prompt rules to general principles

Reviewers pointed out the previous rewrite traded one prompt smell (over-
permissive verbatim quoting) for another (too many specific rules and
exhaustive bilingual example tables). Rewrites the description block as
general principles with a single representative example each, trusting the
model to generalize:

- "Strip non-spec material before writing" replaces the multi-bullet list
  of routing-meta-instruction and conversational-filler enumerations.
- "Include Context only when references were fetched and produced facts;
  never use it as an apology log" replaces the three "Do NOT emit a
  Context section to" sub-bullets.
- The CC exception (the only operationally non-obvious rule, since
  `multica issue create` has no --subscriber flag) is kept inline as a
  single sentence and is still locked in by the regression test.

Net: ~16 fewer lines of prompt text without losing any of the rules the
test asserts.
