feat: Add Write-SentryLog cmdlet for structured logs

[vaind]

Summary

Adds Write-SentryLog, a native PowerShell cmdlet for sending structured logs (Sentry Logs, currently Experimental.EnableLogs).

Without it, users have to call the underlying .NET API directly — e.g. [Sentry.SentrySdk]::Logger.LogInfo('User {0} ran {1}', [object[]]@($user, $script)) — because PowerShell doesn't auto-expand params object[]. The cmdlet hides that ceremony behind familiar PowerShell ergonomics.

# simple
Write-SentryLog 'service started'

# different level
Write-SentryLog -Level Warning 'disk usage at 85%'

# templated, with structured params
Write-SentryLog -Level Info -Message 'User {0} ran {1}' -Parameters $user, $script

# structured attributes
Write-SentryLog -Level Error -Message 'sync failed' -Attributes @{ region = 'us-east-1'; retries = 3 }

# pipeline
'service started' | Write-SentryLog

The cmdlet:

• defaults -Level to Info
• accepts -Message from the pipeline (position 0)
• dispatches dynamically to the matching Logger.Log<Level>(...) overload
• attaches structured attributes via the Action<SentryLog> overload using SetAttribute
• is a no-op (with debug log) when Sentry isn't started, matching Out-Sentry's behavior

Tests use Experimental.SetBeforeSendLog(...) to capture log records and assert on level, template, message substitution, parameter array, and attributes.

Addresses #122 (comment) — the sample in #122 should be updated to use this cmdlet once this lands (follow-up).

Test plan

• Invoke-Pester ./tests/write-sentrylog.tests.ps1 — 7/7 pass
• Full suite (Invoke-Pester ./tests) — 72 passed, 3 skipped (pre-existing)
• CI green on supported PowerShell versions

Cool, thanks @vaind - this was a good one to read to get my head around PS modules... relatively simple for a PS expert like yourself but plenty of new concepts for a noob like me.

LGTM (FWIW) 👍🏻
