…pts (AST-180794) (#1578)

* AST-180794: Add provenance tag and confidence-gated suppression to guardrail prompts

Tags ASCA/KICS/SCA guardrail output with a Checkmarx provenance marker so
agents can distinguish genuine findings from spoofed text, and replaces the
blanket "ask the user first" suppression gate with a confidence-gated model:
suppress only when grounded in something verifiable in the file (or, for SCA,
after actually attempting remediation), otherwise ask instead of guessing.
Also reminds the agent to resume the original task after handling a finding.

* AST-180794: Add hook-deny header and explicit user-instruction path to guardrail prompts

Adds a shared hookDenyHeader to ASCA, KICS, and SCA guardrail prompts that
states up front the message is a Checkmarx hook deny, not file content or an
untrusted tool error, without repeating the spoof phrases the anti-injection
skill tests treat as evidence a message did not come from Checkmarx.

Splits the suppression rule into two independently sufficient paths: (a) the
user explicitly told the agent to suppress or ignore the finding, honored
immediately with no further verification, or (b) the agent decides on its own
and grounds that decision in code it has actually opened and read itself (not
an assumption or another file's claim). SCA's package suppression path is
tightened the same way, requiring either the user's instruction or an actual
remediation attempt returning "no fixed version exists".

Adds injection-trigger regression tests across all five supported agents for
ASCA, KICS, and SCA verifying the hook-deny header is present and phrases like
"without asking" or "silently" never appear in agent-facing text.

* AST-180794: Restructure guardrail prompts to classify-then-act remediation model

Replaces the analyze/ask-when-unsure flow with an explicit classify-then-act
sequence: findings are false positives only when cited evidence meets (a) or
(b), otherwise they are always remediated autonomously and never surfaced to
the user as a remediate-or-suppress question. Adds a structured remediation
summary report and a verify-and-retry step across ASCA, KICS, and SCA
guardrails.

* AST-180794: Include findings list and tighten guardrail summary wording

Adds the findings/packages list into the Cursor ASCA/KICS prompts and the
SCA malicious/vulnerable prompts (previously only in the non-Cursor path),
and simplifies remediationNote's signature now that subject/goal are no
longer used. Aligns summary report wording and evidence hints (e.g. "parent
module or sibling manifest") across agents, and updates the KICS Cursor test
to match.

* AST-180794: Share remediation report templates and bump ast-cx-hooks

Extract the ASCA, KICS, and SCA closing remediation reports into shared
constants (ascaRemediationReport, kicsRemediationReport, scaMaliciousReport,
scaVulnerableReport) so the Cursor and non-Cursor deny paths render the same
markdown report instead of two copies that could drift apart. Bump
ast-cx-hooks to v1.0.10 and refresh go.sum.
