* feat: emit cloud events for dependency cooldown and host observations (#237)
Wire cooldown blocks and proxy host observations through the cloud sync
pipeline so they appear as telemetry in Control Tower.
- Cooldown blocks emit PACKAGE_DECISION with COOLDOWN_BLOCKED action and
PmgDependencyCooldown context (publish date, cooldown days, days since
publish, days remaining)
- Proxy host observations emit HOST_OBSERVATION with PmgHostObservation
(hostname, method)
- Session summary now includes cooldown_blocked_count
- Updated buf API dependency for new proto schema

* fix: add explicit eventlog mapping for EventTypeDependencyCooldown
Follow the existing pattern where every audit event type has an explicit
case in mapEventType and a corresponding constant in the eventlog package.

* feat: Show cooldown report for pinned version installs
When a user installs a package with an explicit version (e.g.
npm install foo@1.2.3) and that version falls within the dependency
cooldown window, the cooldown block is now recorded and shown in the
report. Previously, the report only appeared when ALL versions of a
package were in cooldown (remaining == 0), causing pinned version
installs to fail with a confusing "version not found" error from the
package manager instead of a clear cooldown explanation.
Introduces InterceptorContext to carry per-execution data (pinned
versions) from the CLI command through the interceptor layer, keeping
it separate from long-lived dependencies like the analyzer and cache.
* fix: Normalize PyPI pinned version keys for cooldown lookup
CLI-provided package names (e.g. Flask_Cors) don't match the
URL-parsed form (flask-cors). Normalize keys once at construction
time so cooldown lookups match correctly.
* fix: Handle dots in PyPI package name normalization per PEP 503
denormalizePyPIPackageName already documented [-_.] replacement but
only handled underscores. Now also replaces dots with hyphens so
names like zope.interface match the URL-parsed form zope-interface.
* refactor: Extract shared cooldown stats recording into helper
Deduplicate identical stats-recording blocks from npm_cooldown.go
and pypi_cooldown.go into recordCooldownStats in cooldown.go.
* fix: Distinguish explicit version pins from auto-resolved versions
PyPI parsers resolve all packages to concrete versions (even without
a user-specified constraint), so HasVersion() was always true. Add
IsExplicitVersion to PackageInstallTarget, set it only when the user
provided an explicit constraint. Use it in proxy_flow.go to avoid
false pinned-version cooldown reports.
* refactor: Extract shared cooldown helpers to package-level functions
* feat: Add PyPI cooldown handler with PEP 691 file parsing
* feat: Add PyPI cooldown file stripping logic
* feat: Implement PyPI cooldown HandleMetadataRequest with PEP 691 filtering
* feat: Wire PyPI cooldown into pypi_registry interceptor
* update headers for no cache
* fix: Strip conditional GET headers to prevent 304 bypass in cooldown handlers
pip and npm clients cache Simple API / registry responses with ETags. On
subsequent requests they send If-None-Match, which causes the server to
return 304 Not Modified with no body. The cooldown response modifier
received an empty body, failed to parse it, and failed-open — letting
the client use its stale cached (unfiltered) response.
Fix: delete If-None-Match and If-Modified-Since from the request before
forwarding, forcing a full 200 response so the modifier always has a
body to filter.
Also removes the Content-Type guard from the PyPI modifier (the empty
Content-Type on 304 responses was a symptom of the same root cause) and
replaces Cache-Control: no-cache with the more targeted header deletion.
