feat: implement IRC numerics batch 2 — connection registration, channel ops, user queries

Browse Source 
Add comprehensive IRC numeric reply support:

Connection registration (001-005):
- 002 RPL_YOURHOST, 003 RPL_CREATED, 004 RPL_MYINFO, 005 RPL_ISUPPORT
- All sent automatically during session creation after RPL_WELCOME

Server statistics (251-255):
- RPL_LUSERCLIENT, RPL_LUSEROP, RPL_LUSERCHANNELS, RPL_LUSERME
- Sent during connection registration and via LUSERS command

Channel operations:
- MODE command: query channel modes (324 RPL_CHANNELMODEIS, 329 RPL_CREATIONTIME)
- MODE command: query user modes (221 RPL_UMODEIS)
- NAMES command: query channel member list (353/366)
- LIST command: list all channels (322 RPL_LIST, 323 end of list)

User queries:
- WHOIS command: 311/312/318/319 numerics
- WHO command: 352 RPL_WHOREPLY, 315 RPL_ENDOFWHO

Database additions:
- GetChannelCount, ListAllChannelsWithCounts
- GetChannelCreatedAt, GetSessionCreatedAt

Also adds StartTime to Globals for RPL_CREATED and updates README
with comprehensive documentation of all new commands and numerics.

**IRC reference:** RFC 1459 §4.6.2, §4.6.3
#### MODE — Set/Query Modes (Planned)
#### MODE — Query Modes
Set channel or user modes.
Query channel or user modes. Returns the current mode string and, for
channels, the creation timestamp.
**C2S:**
```json
{"command": "MODE", "to": "#general", "params": ["+m"]}
{"command": "MODE", "to": "#general", "params": ["+o", "alice"]}
{"command": "MODE", "to": "#general"}
{"command": "MODE", "to": "alice"}
```
**Status:** Not yet implemented. See [Channel Modes](#channel-modes) for the
planned mode set.
**S2C (via message queue):**
For channels, the server sends RPL_CHANNELMODEIS (324) and
RPL_CREATIONTIME (329):
```json
{"command": "324", "to": "alice", "params": ["#general", "+n"]}
{"command": "329", "to": "alice", "params": ["#general", "1709251200"]}
```
For users, the server sends RPL_UMODEIS (221):
```json
{"command": "221", "to": "alice", "body": ["+"]}
```
**Note:** Mode changes (setting/unsetting modes) are not yet implemented.
Currently only query is supported.
**IRC reference:** RFC 1459 §4.2.3
#### NAMES — Channel Member List
Request the member list for a channel. Returns RPL_NAMREPLY (353) and
RPL_ENDOFNAMES (366).
**C2S:**
```json
{"command": "NAMES", "to": "#general"}
```
**IRC reference:** RFC 1459 §4.2.5
#### LIST — List Channels
Request a list of all channels with member counts. Returns RPL_LIST (322)
for each channel followed by RPL_LISTEND (323).
**C2S:**
```json
{"command": "LIST"}
```
**IRC reference:** RFC 1459 §4.2.6
#### WHOIS — User Information
Query information about a user. Returns RPL_WHOISUSER (311),
RPL_WHOISSERVER (312), RPL_WHOISCHANNELS (319), and RPL_ENDOFWHOIS (318).
**C2S:**
```json
{"command": "WHOIS", "to": "alice"}
```
**IRC reference:** RFC 1459 §4.5.2
#### WHO — Channel User List
Query users in a channel. Returns RPL_WHOREPLY (352) for each user followed
by RPL_ENDOFWHO (315).
**C2S:**
```json
{"command": "WHO", "to": "#general"}
```
**IRC reference:** RFC 1459 §4.5.1
#### LUSERS — Server Statistics
Request server user/channel statistics. Returns RPL_LUSERCLIENT (251),
RPL_LUSEROP (252), RPL_LUSERCHANNELS (254), and RPL_LUSERME (255).
**C2S:**
```json
{"command": "LUSERS"}
