feat(policy): add memory:PutBioTables and memory:DeleteBioTables actions

[dilverse]

Problem

The AIStor Memory API has no action that authorizes provisioning an agent's OpenTelemetry tables.

Those tables are created today by whichever client writes telemetry first, so their names and schemas can drift between the
ingest sidecar, the console and the CLI. A drift is only discovered when one writer fails against a table another client
created, and the failure surfaces far from the change that caused it.

Moving that definition to a single server-side owner needs a resource family of its own — biotables, addressed as
arn:minio:memory:::<cortex>/biotables/<agent>. No existing action authorizes it. memory:PutAgent is the wrong one: it
writes agent state, while provisioning telemetry writes the Tables catalog, so a principal allowed to write an agent must not
gain it by default.

Fix

• memory:PutBioTables and memory:DeleteBioTables, registered in SupportedMemoryActions so they validate, parse and match.
• Both are point actions. Each names one agent's tables and carries no query to constrain, so neither accepts memory:prefix
  or memory:max-keys. TestMemoryEnumerationConditionKeys now asserts that, alongside the existing read and write actions.
• memory:PutAgent's doc comment now says it covers a memory beneath an agent as well as the record itself, which is what the
  action has always authorized.

No behaviour changes for any existing action.

Verification

$ go test ./policy/... -count=1
ok  	github.com/minio/pkg/v3/policy	0.631s
ok  	github.com/minio/pkg/v3/policy/condition	0.414s

$ make lint
Running lint check
0 issues.

Negative verification — dropping one registration from SupportedMemoryActions and re-running:

--- FAIL: TestMemoryActionIsValid (0.00s)
    memory-action_test.go:52: case 9: action memory:PutBioTables: expected: true, got: false
FAIL	github.com/minio/pkg/v3/policy	0.283s

Restored, and the suite is green again.

Also included

Nothing. The branch is three files, all under policy/.

Not fixed

The consumer in miniohq/eos is not part of this PR. It depends on these two actions and will follow once this lands and the
dependency is bumped.

Summary by CodeRabbit

• New Features

  • Added policy actions for creating and deleting telemetry memory tables.
  • Updated agent memory permissions to include writing memories beneath an agent.

• Bug Fixes

  • Improved validation for table actions by rejecting unsupported memory prefix and maximum-key conditions.
  • Added coverage to verify the new actions are recognized as valid policy options.

📝 Walkthrough

Walkthrough

The policy package adds put and delete actions for agent telemetry tables. It registers both actions as supported Memory actions and updates tests for action validity and point-action condition-key rejection.

Changes

Memory policy actions

Layer / File(s)	Summary
Define and register telemetry actions policy/memory-action.go	Adds MemoryPutBioTablesAction and MemoryDeleteBioTablesAction, updates MemoryPutAgentAction documentation, and registers both actions.
Validate action semantics policy/memory-action_test.go, policy/memory-resource_test.go	Validates both actions and requires point actions to reject memory:prefix and memory:max-keys condition keys.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: ⚪ Minimal · up to 703b9

This adds explicit authorization for provisioning and deleting an agent’s telemetry tables without changing existing action behavior. The change is localized and verified by passing policy tests and lint, so no actionable merge-blocking risk remains.

Poem

A rabbit checks the policy page,
Two table actions join the stage.
Put and delete now pass the gate,
Prefix and key limits meet their state.
The memory rules are neat and bright—
Hop, hop, reviewed just right!

MemoryPutBioTablesAction and MemoryDeleteBioTablesAction alongside the existing

will redo this as a single API instead of introducing the biotables as a new api
